Can someone kindly help me with this qn.
Miss Kan bought some candies. She divided the candies equally among a class of 28 children. 3 of them have all their candies to the rest of the children. As a result, the rest of the children received 9 more candies each. How many candies did each child receive at first?
Another qn:
A shopkeeper had 377 pens n files. After he sold 4/7 of his pens and bought another 28 files, the umber of files he had became 2/3 the number of pens. How many files had he at first? -
25 children get 9 more. So total given out by 3 children is 9x25 is 225. Each of the 3 child gave 225/3 is 75.

before
P[][][][][][][]
F[ ] ............... }Total of P&F 377
After
P[][][][][][][]
F[][] ................................ }Total of P&F 377+28=405
u=405/9=45
Ans=90-28=62 -
At first pen is 7 unit; file is 377 - 7unit
then pen sold 4 unit left 3 unit; file is 377-7unit +28 = 2 unit
so 377+28 =9 unit
1 unit is 405/9=45
at first file is 377-7unit=377-315=62 -

still u need help on this qn?Another question:
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! -
