Solution and Explanation
Total Funds Raised in 2015
Constraints:
- Each firm raises ₹1 crore in its initial and final years of operation.
- Annual fund amounts vary by ₹1 crore or ₹2 crores from the previous year.
- No firm raises the identical amount in consecutive years.
Firm Data:
| Firm | Years Active | Total Raised |
|---|---|---|
| Alfloo | 2009–2016 (8 years) | ₹21 crore |
| Bzygoo | 2012–2015 (4 years) | Unknown |
| Drjbna | 2011–2015 (5 years) | ₹10 crore |
Analysis:
- Drjbna: ₹1 crore raised in 2011 (first year) and ₹1 crore in 2015 (last year), totaling ₹2 crore.
- The remaining ₹8 crore must be distributed across 2012, 2013, and 2014. Possible sequences that adhere to the ₹1/₹2 crore change and no consecutive identical amounts exist. For example, a sequence of ₹2 crore, ₹4 crore, ₹2 crore yields ₹8 crore for these years. Therefore, Drjbna's amount in 2015 is ₹1 crore.
- Bzygoo: Operates for 4 years. ₹1 crore raised in the first year and ₹1 crore in the last year, totaling ₹2 crore. The remaining amount must be distributed across the two middle years (2013 and 2014). For instance, if the middle years raise ₹3 crore and ₹2 crore respectively, the total raised by Bzygoo would be ₹1 + ₹3 + ₹2 + ₹1 = ₹7 crore. If the middle years raise ₹2 crore and ₹3 crore respectively, the total raised by Bzygoo would be ₹1 + ₹2 + ₹3 + ₹1 = ₹7 crore. Other combinations are possible, leading to a total of ₹7 crore as one potential scenario.
Conclusion: Considering Drjbna raised ₹1 crore in 2015 and Bzygoo raised ₹6 crore total (with ₹1 crore in 2015), the combined total for 2015 could be ₹1 + ₹1 = ₹2 crore. Evaluating all valid combinations reveals other possibilities.
Final Answer:
The most probable total amount raised in 2015 is ₹7 crore.

| 1 | 3 | 5 | 3 | 1 | - | |
| 1 | 2 | 3 | 4 | 2 | 1 | |
| 1 | 2 | 4 | 3 | 2 | 1 |
The highest amount of money raised in 2013 was:
$5 + 3 + 1 + 4 + 4 = 17$

The Correct Option is C
Solution and Explanation
To resolve this issue, we examine the given parameters and known figures. For each company:
- The initial and final fundraising amounts are ₹1 crore.
- Fundraising amounts increase and subsequently decrease by ₹1 crore or ₹2 crores annually.
- Fundraising amounts cannot be identical in two consecutive years.
Provided Information:
- Elavalaki raised ₹3 crores in 2013.
- Elavalaki commenced operations in 2010 and accumulated a total of ₹13 crores.
Hypothesized Annual Pattern for Elavalaki (aiming for a total of ₹13 crores):
| Year | Amount Raised (₹ crores) |
|---|---|
| 2010 | $1$ |
| 2011 | $3$ |
| 2012 | $5$ |
| 2013 | $3$ |
| 2014 | $1$ |
Summation = $1 + 3 + 5 + 3 + 1 = 13$ crores ✅
Therefore, Elavalaki's fundraising in 2012 was ₹5 crores.
Other Companies:
- Alfloo: Maximum cumulative total of ₹21 crores. Selecting the lowest possible value for 2012 results in an assumed ₹2 crores.
- Bzygoo: Lacking specific data, ₹2 crores is assumed as a reasonable minimum for 2012.
- Drjbna: Total of ₹10 crores; 2012 should be close to the minimum. ₹2 crores is assumed.
- Czechy: Started in 2013, hence ₹0 in 2012.
Aggregate Fundraising in 2012:
$5 + 2 + 2 + 2 = \mathbf{11}$ crores
Conclusion: ₹11 crores represents the lowest achievable total amount raised by all companies in 2012.

- Bzygoo raised the same amount of money as Elavalaki in 2013.
Hide Solution
The Correct Option is D
Solution and Explanation
To identify the impossible scenario, we use the following information and constraints:
- Each firm's first and last year of operation involved raising Rs. 1 crore.
- Annual fundraising amounts for any firm could not be consecutive. Annual changes were limited to Rs. 1 crore or Rs. 2 crores.
Examining each firm:
- Alfloo (2009-2016): Total raised: Rs. 21 crores. Fundraising sequence: Rs. 1 crore (2009), subsequent fluctuations, concluding with Rs. 1 crore in 2016.
- Bzygoo (2012-2015): Total unknown. Possible fundraising amounts:
| Year | Amount Raised |
|---|---|
| 2012 | 1 |
| 2013 | x (2 or 3) |
| 2014 | y (3, 4, or 5) |
| 2015 | 1 |
- Bzygoo's total: 1 + x + y + 1 = 2 + x + y, dependent on x and y.
- Czechy (2013-unknown): Total raised: Rs. 9 crores.
- Drjbna (2011-2015): Total raised: Rs. 10 crores. Possible sequences: 1-2-3-2-1 or 1-3-2-3-1.
- Elavalaki (2010-unknown): Total raised: Rs. 13 crores; similar progression logic applies.
Evaluating each possibility:
- Bzygoo raised more than Elavalaki in 2014: This is possible if Bzygoo's 2014 amount (y) exceeds Elavalaki's 2014 amount, given flexible yearly allocations.
- Alfloo's total equaled Bzygoo's 2014 amount: This is possible through matching increases or decreases in fundraising.
- Alfloo's total equaled Drjbna's 2013 amount: Considering Alfloo's cumulative total, a match is feasible.
- Bzygoo's amount equaled Elavalaki's 2013 amount: This scenario contradicts Elavalaki's known annual progression.
Conclusion:
Bzygoo raised the same amount of money as Elavalaki in 2013, which contradicts Bzygoo's potential yearly fundraising figures.
