Mahesh donates 7% of his monthly salary R to charity and spends Rs. 3000 per month on his house rent. What is the balance amount out of his monthly salarly ?
(A) R @ 7 * R # 100 $ 3000
(B) R @ 3000 @ 7 *100 # R
(C) R @ (R * 7 # 100 $ 3000)
Total salary = R
Salary donated and spent on rent = $$(\frac{7}{100}\times R)+3000$$
=> Balance amount = $$R-(\frac{7R}{100}+3000)$$
(A) : R @ 7 * R # 100 $ 3000
=> $$R-7\times R\div 100+3000=R-\frac{7R}{100}+3000$$
(B) : R @ 3000 @ 7 *100 # R
=> $$R-3000-7\times100\div R=R-3000-\frac{700}{R}$$
(C) : R @ (R * 7 # 100 $ 3000)
=> $$R-(R\times7\div100+3000)=R-(\frac{7R}{100}+3000)$$
=> Ans - (C)
