Question

Raj borrows Rs.8,000; out of which Rs. 4500 at 5% and the remainder at 6%. Find the total interest paid by him in 4 years.

Answer 1

Total sum borrowed by Raj = Rs.8000

In the First Case :

P = Rs.4500

R = 5%

T =4 years

S.I. =`("P"xx"R"xx"T")/100`

= Rs.`(4500xx5xx4)/100`

= Rs.900

In the Second Case :

p = Rs.8000 − Rs.4500

= Rs.3500

R = 6%

T = 4 years

S.I. =`("P"xx"R"xx"T")/100`

= Rs. `(3500xx6xx4)/100`

= 35 × 6 × 4 = Rs.840

Total interest paid by Raj

= Rs.900 + Rs.840

= Rs.1740
