Ques - A sum was put at simple interest at a certain rate for 2 years. Had it been put at 4% higher rate, it would have fetched Rs. 112 more. The sum is :

(a) 1120

(b) 1400

(c) 1200

(d) 8000

Solution - 

[(P×R×T) / 100] - [(P×R×T) / 100] = 112

[(P × (R + 4) × 2) / 100] - [(P×R×2) / 100] = 112

(2P / 100) [R + 4 - R] = 112

P (4) = 112 × 50

P = 5600 / 4

P = 1400

Therefore,

The sum is 1400.

Hence,

The correct answer is option (b) 1400.
