Before |
5x3 =
15 u |
7 u |

- 4x3 =
- 3 u |
- 4 u |
After |
1x3 =
3 u |
3 u |
(a)
Fraction of the mangoes left
= 1 -
45 =
15 Fraction of the guavas left
= 1 -
47 =
37The number of mangoes and guavas left were the same. Make the number of mangoes and guavas left the same. LCM of 1 and 3 is 3.
Number of mangoes at first = 15 u
Number of guavas at first = 7 u
15 u = 120
1 u = 120 ÷ 15 = 8
Number of mangoes left
= 3 u
= 3 x 8
= 24
(b)
Number of guavas at first
= 7 u
= 7 x 8
= 56
Answer(s): (a) 24; (b) 56
