Question

The simple interest on a certain sum at 5% for 9 months is rs. 10 greater than the simple interest on the same sum at the rate of 3% for 14 months. X = what is the sum of interest in both the cases (i.E. Total sum of interest)? Y = 200

Answer 1

290 will be the interest

Answer 2

Step-by-step explanation:

let principal be P

15/4% for 9 months and 14/4% for 14 months by conversion

P(15/4%)-(14/4%)P=10 rs

solving this, we get P= 4000

putting value of P in (15/4%) P we get 150

simialrly P(14/4%) = 140

adding both 150+140 =290
