smartmummy:
Some old folks are sharing 2 bunches of grapes. If each of them eats 12 grapes, there will be 7 grapes short. If each of them eats 11 grapes, there will be 3 grapes extra. If one bunch of grapes has 19 fewer grapes, find the number of grapes in the larger bunch.TIA
If each person eats 12 grapes, they will be short of 7 grapes.
If each person eats 11 grapes, they have 3 extra.
This means there are 7 + 3 = 10 old folks altogether.
Total number of grapes = 11 x 10 + 3 = 113
1 bunch has 19 fewer grapes than the other bunch.
113 - 19 = 94
94 / 2 = 47
47 + 19 = 66
The larger bunch has 66 grapes.
Enjoy! -
