Question

Suman invested Rs 4000 ina a building society which paid simple interest at the rate of 6℅ p.a . After 2 years the rate was increased to 7½ p.a . Find the amount she received after 5 years

Answer 1

Answer:

The Amount she received After 5 yrs is ₹5380

Step-by-step explanation:

Hey Mate,

Given,

(P) Principle = ₹4000

(T) Time = 5 Years

(R₁) Rate for First 2 yrs = 6%

(R₂) Rate for last 3 yrs = 7.5%

(S.I) Simple Interest = P×R×T/ 100

S.I = {P × R₁ × T / 100} + {P × R₂ × T / 100}

S.I = {4000 × 6 × 2 / 100} + {4000 × 7.5 × 3 / 100}

S.I = 480 + 900

S.I = ₹1380

(A) Amount = Simple interest + Principle

A = 1380 + 4000

A =  ₹5380
