2.  A dealer sold a Radio at a loss of 2.5%. Had he sold it for Rs. 100 more, he would have gained 7.5%. To gain 12.5% he should sell it for :

Rs 2200
Rs 1000
Rs 1100
Rs 1125

```Answer

Answer: Option  D Explanation: Let C.P be Rs.x then,(107.5 % of x) – (97.5 % of x) = 100
=> 10% of x = 100
=> x =1000
∴ desired S.P = 112.5 % of Rs. 100
= Rs.(225/2 x 1/100 x 1000) =Rs. 1125 ```

4.  A man buys two horses for Rs. 1550. He sells one so as to lose 23% and other so as to gain 27%. On the whole transaction he neither gains nor loses. What does each horse costs?

807,743
817,733
827,723
837,713

```Answer

Answer: Option  D Explanation: Let CP of one be X and other be Y
X+Y = 1550….(i)
ATQ:-
0.77X + 1.27Y = 1550…(ii) (as no profit and no loss is there)
Solving both, we get
50Y = 35650 or Y = 713
Hence, X = 1550-713 = 837
Therefore, CP of each horse = 837,713 ```
