  1. A certain sum at simple interest amounts to Rs 1040 in 3 Yr and to Rs 1360 in 7 yr.Then the sum is ?
    1. Rs 750
    2. Rs 800
    3. Rs 900
    4. Rs 1000
  1. Correct Option: B

    Simple Interest for 4 yr = Rs(1360 - 1040 ) = Rs 320
    so, Simple Interest for 3 yr= Rs [(320/4) x 3]= Rs 240

    Sum = Rs (1040-240)= Rs 800
