Question:
Manavi and Kuber each receives an equal allowance. The table shows the fraction of their allowance each deposits into his/her saving account and the fraction each spends at the mall. If allowance of each is ₹ 1260 find the amount left with each.
Solution:
From the question,
Manavi and Kuber each receives and equal allowance = ₹ 1260
Let us assume total cost be ₹ 1
For Manavi, left over = Total cost – Total spends
= 1 – (½ + ¼)
= 1 – (2 + 1)/4
= 1 – (3/4)
= (4 – 3)/4
= ¼
So, Amount = 1260 × ¼ = ₹ 315
For Kuber, left over = Total cost – Total spends
= 1 – (1/3 + 3/5)
= 1 – (5 + 9)/15
= 1 – (14/15)
= (15 – 14)/15
= 1/15
So, Amount = 1260 × (1/15) = ₹ 84
