1)   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?

a. Rs. 6400
b. Rs. 6500
c. Rs. 7200
d. Rs. 7500
Answer  Explanation 

ANSWER: Rs. 6400

Explanation:
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.
