a) 500, 300
b) 200, 400
c) 400, 200
d) 300, 500
Answer: c
Explanation: Let X be the cost of horse and Y be the cost of the cart.
10% of loss in selling horse = 20% of gain in selling the cart.
$$\frac{{10}}{{100}} \times {\text{X}}$$ = (20 × 100) × Y
X = 2y ————–(1)
5% of loss in selling horse is 10 more than the 5% gain in selling the cart.
Therefore, $$\frac{5}{{100}} \times {\text{X}} – 10 = \frac{5}{{100}} \times {\text{Y}}$$
5X – 1000 = 5Y
Using equation (1),
10Y – 1000 = 5Y
5Y = 1000
Y =200
X = 400
CP of Horse = Rs. 400
CP of the Cart = Rs. 200
