| 3) | 20 kg | 4) | 25 kg |
| 5) | None of these | ||
Answer : 20 kg
Explanation : Let, the shopkeeper sell x kg at 20% profit. He sell (100 -x) kg at 10% profit.
Explanation : Let, the shopkeeper sell x kg at 20% profit. He sell (100 -x) kg at 10% profit.
So, 120x/100 + 110(100-x)/100 = 100 X 112/100
or 120x - 110x = (100 X 112 -110 X 100 ) = 200
or 10x = 200
or x =200/10 = 20 kg.

| 3) | 20 | 4) | 25 |
| 5) | None of these | ||
Answer : 16
Explanation :

Let , C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
So, (20 -x) /x = 25
or 2000 - 100x = 25x
or 125x = 2000 or x = 2000/125 =16
