Question

The simple interest on a sum of money for 5 years at 6 % p.a. is ₹ 120 more than the interest on the same sum at 5% p.a. for 4 years . Find the sum invested.​

Answer 1

Answer:

RS 300

Step-by-step explanation:

1st sum of money:

P = Rs 120

R = 6%

T = 5 years

SI = PRT/100

= 120 x 6 x 5 / 100

= 3600 / 100

= Rs 36

Amt = Rs 120 + 36 = Rs 156

2nd sum of money:

P = Rs 120

R = 5%

T = 4 years

SI = PRT/100

= 120 x 5 x 4 / 100

= 2400 / 100

= Rs 24

Amt = Rs 120 + 24 = Rs 144

∴Total Amt = Rs 156 + Rs 144 = Rs 300
