15 years old get 33-year interest
13 years old get 5 years interest
Difference of interest get = 5-3 = 2 Convert ratio into percentage = 4%

Here, Assume 1 is interest and 25 is principal amount
So, compound interest = 25 + 1 = 26

A +B = 12
B +C =6 ²/₃
A +B +C’s total work together

Total 60 units and 1 day’s work is units
3A + 4B + 7C = 60 units
3A + 3B + 1B + 1C + 6C = 60 units
3(A + B) + 1(B + C) + 6C = 60 units
3(5) + 1(9) + 6C = 60
15 + 9 +6C = 60
6C = 60 – 24
6C = 36
C = 6
A = 2, B = 3, C = 6
A’s 1 day work = 2 units
A’s total work in how many days = 60 units

Ans 8. 111 minutes

1st minute a monkey will climb 5 cm and in 2nd minute it come 4 cm down.
