printing mistake (Question: 181626.2 )

there should be ppf in the question

Question:
DIRECTIONS: Answer these questions on the basis of the information given below. 


In the Shah household, one of Mr. or Mrs. Shah would take care of all expenses under a head, among the different head of expenses incurred by the family. The first two pie charts gives the percentage distribution of the expenses incurred by each of Mr. and Mrs. Shah and their savings, out of their salaries. The third pie chart gives the percentage distribution on various heads, of the investment of their combined savings.







If investments in PPF was Rs.36,000 annually, then which of the following could be their average monthly expenses for entertainment, if one of them earned half as much as the other?
Options:
A) Rs.5000
B) Rs.6000 
C) Rs.10000 
D) Rs.12000
Solution:
Ans: (c) The total savings = Rs.1,20,000

Now there are two possibilities.

Case (1):

Mr. Shah earns twice as much as Mrs. Shah.

∴ 0.2(2y) + 0.1y = 1,20,000

∴ y = 2,40,000 and x = 4,80,000

∴ Entertainment = \(\cfrac{20}{100}\) × 2,40,000 = Rs.48,000

Case (2):

If Mr. Shah earns half as much as Mrs. Shah.

∴ 0.2(0.5y) + 0.1y = 1,20,000

⇒ 0.2y = 1.20000

y = 6,00,000

∴ Expenses on entertainment = Rs.1,20,000

∴ Monthly expenses in the first case is Rs.4000 and in the second case is Rs.10,000.
