about method (Question: 190593.0 )

in end 484560 is divide by 20 not 12

Question:
Mr. Yadav spends 60% of his monthly income on electric appliances and 50% of the remaining on clothes and transportation. If he saves Rs. 484560 annually, then what amount does he spend on clothes and transportation monthly ?
Options:
A) Rs. 40380
B) Rs. 8076
C) Rs. 9691.20
D) Rs. 4845.60
Solution:
Ans: (a) Let the monthly income of Mr. Yadav 

= Rs. 100 

expense on electricity = 60% of 100 = Rs. 60 

expense on clothes & transportation = 50% of (100 -60) 

= \(\cfrac{50}{100}\) × 40 = Rs. 20 

\(\therefore \) saving = 40 - 20 = Rs. 20 

\(\Rightarrow\) Expense on clothes & transportation 

= saving = Rs. 20 

\(\therefore \) Monthly expense on clothes & transportation = \(\cfrac{484560}{12}\) = Rs. 40380

Since Savings = expense on clothes and transportation and yearly savings are given as 484560.

Therefore monthly expense on clothes and Transportation / monthly savings comes by diving 484560 by 12.


Hope it helps.
