| Before |
5x2 =
10 u |
+ 75 |
10x1 =
10 u |
| Change |
- 4x2 =
- 8 u |
- 60 |
- 3x1 =
- 3 u |
| After |
1x2 =
2 u |
+ 15 |
7x1 =
7 u |
Comparing chikoos
and apples in the end |
30 less |

80% =
80100 =
45 80% x 75 =
45 x 75 = 60
75 - 60 = 15
30% =
30100 =
310 The number of chikoos is 30 less than the number of apples in the end. So, if another 30 chikoos are added, the number of chikoos and apples in the end will be the same.
2 u + 15 + 30 = 7 u
2 u + 45 = 7 u
7 u - 2 u = 45
5 u = 45
1 u = 45 ÷ 5 = 9
Number of apples left
= 7 u
= 7 x 9
= 63
Total number of fruits left
= 2 u + 15 + 7 u
= 9 u + 15
= 9 x 9 + 15
= 81 + 15
= 96
