Some capsules were bought for Rs. 176. If the price of each capsule had been Rs. 3 less, 6 more capsules would have been bought for the same amount. What was the number of capsules bought ?
1). 13
2). 16
3). 17
4). 8
Let capsules bought = $x$
Acc. to ques,
=> $\frac{176}{x} - \frac{176}{x + 6} = 3$
=> $\frac{176 \times 6}{x (x + 6)} = 3$
=> $x (x + 6) = 352 = 22 \times 16$
=> $x (x + 6) = 16 (16 + 6)$
=> $x = 16$
