Question
Mr. Tassawar Javed invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in Scheme B?
Answer: Option A
LET THE SUM INVESTED IN SCHEME A BE RS. X AND THAT IN SCHEME B BE RS. (13900 – X).
THEN , (X*14*2/100)+(13900-X)*11*2/100) =3508
28X – 22X = 350800 – (13900 X 22)
6X = 45000
X = 7500.
SO, SUM INVESTED IN SCHEME B = RS. (13900 – 7500) = RS. 6400.
