Answers
it's a incomplete question
Answer:
Step-by-step explanation:
Let the total number of grandchildren = x
Let the amount received by each grandchild = Rs y
Total money distributed by grandfather = Rs xy
CASE 1:Number of grandchildren = x-3
amount received by each grandchild = Rs y+60
Total money distributed by grandfather = Rs xy
⇒x-3y+60 = xy
⇒xy + 60x - 3y - 180 = xy
⇒60x - 3y = 180
⇒20x - y = 60
1CASE 2:Number of grandchildren = x+2
amount received by each grandchild = Rs y-20
Total money distributed by grandfather = Rs xy
⇒x+2y-20 = xy
⇒xy -20x + 2y - 40 = xy
⇒-20x + 2y = 40
⇒-10x + y = 20
..........2Adding 1 and 2, we get 10x = 80
⇒x = 8
Put x = 8 in 1,
we get 20 × 8 - y = 60
⇒160 - y = 60
⇒y = 100
So, total number of grandchildren = 8
amount received by each grandchild = Rs 100
