Answer 1

Answer:

Solution(By Examveda Team)

Let the sum invested in Scheme A be Rs. x and that in Scheme B be Rs. (13900 - x)

Then,

x×14×2100+

(13900−x)×11×2100

=3508

⇒ 28x - 22x = 350800 - (13900 x 22)

⇒ 6x = 45000

⇒ x = 7500

So, sum invested in Scheme B

= Rs. (13900 - 7500)

= Rs. 6400
