Vishwas borrowed a total amount of Rs. 30,000 part of it on simple interest, rate of 12 p.c.p.a. and remaining on simple interest rate of 10 p.c.p.a. If at the end of 2 years he paid in all Rs. 36,480 to settle the loan amount, what was the amount borrowed at 12 p.c.p.a.?
A Rs. 16000
B Rs. 18000
CRs. 17500
DRs. 12000

Correct answer is: Rs. 12000

Explanation:

Let the sum borrowed at 12% p.a. be Rs. x
and that borrowed at 10% p.a. be Rs. (30000 - x)
S.I. at the end of 2 years
= Rs. (36480 - 30000)
= Rs. 6480

(x×12×2100)+[(30000x)×10×2100]=648024x+60000020x=6480004x=48000x=12000.
