1 (Question: 123657.0 )

what is 30% 60% 65% can u explain it in detail

Question:
Mr. More spent 20% of his monthly income on food and 15% on children’s education, 40% of the remaining he spent on entertainment and transport together and 30% on medical. He is left with an amount of \(\unicode{x20B9} \)8775 after all these expenditures. What is Mr. More’s monthly income?
Options:
A) Rs 40,000 
B) Rs 35,000 
C) Rs 42,000 
D) Rs 38,000 
E) None of these
Solution:
Ans:(e)

Total spent on Food+Education=20%+15%=35%

 i.e 100\(\times\)\(\left ( \cfrac {35}{100} \right ) \)

=35x Remaining=100x - 35x = 65x

Total spent on entertainment+Transport+Medical=70%

i.e \(65x\left ( \cfrac {70}{100} \right )\) =45.5x 

Remaining=65x - 45.5x = 19.5x

19.5x = 8775

 ∴ x=\(\cfrac{8775}{19.5}\) = 450 

monthly income of Mr. More =100x 

=100×450 =45000

Hence monthly income is Rs. 45000
