Solution
Given• A can do a piece of work in 24 days.
• A and B together can-do same piece of work in 16 days
To find• In how many days B can complete 2 times more work if B work with 50% more efficiency
Approach and Working out• In 24 days, A is completing the work.
o So, in 16 days, A will complete 16/24 or 2/3 of work.
o Thus, 1/3 of work is completed by B in 16 days.
In 16 days, A is doing 2/3 of word and in same number of days, B is doing 1/3rd of work.
• So, A’s efficiency is half of A.
• Hence, B will complete the same work in twice the time i.e. in 48 days.
o So, 2 times more work will be complete in 48*3 days.
o If B’s efficiency is increased by 50% then work will be done in 96/1.5 time.
Hence, option d is the correct answer.
Correct Answer: Option dHey Payal
Can you please explain this segment

o If B’s efficiency is increased by 50% then work will be done in 96/1.5 time.
=96 days.
As per my understanding
B can finish with improved efficiency the same work in 32 days
so to do the work that is twice he should have taken 32*2 = 64 days
Can you please help where did I miss
