Lemons |
Mangoes |
Before |
3x1 = 3 u |
7x1 = 7 u |
Change |
No change |
- 30 |
After |
3x1 = 3 u |
1x1 = 1 u |
30% =
30100 =
310 75% =
75100 =
34 The number of lemons remains unchanged at first and in the end. Make the number of lemons the same. LCM of 3 and 3 is 3.
Number of mangoes removed
= 7 u - 1 u
= 6 u
6 u = 30
1 u = 30 ÷ 6 = 5
Number of mangoes
= 7 u
= 7 x 5
= 35
Answer(s): 35
