1.	If Mohan’s income is 25% more than Raman’s income, then Raman’s income is less than Mohan’s income by(a) 25% (b) 80% (c) 20% (d) 75%
Answer» (c) 20% Let us assume Mohan’s income be ‘P’ and Raman’s income be ‘Q’ From the question it is given that, Mohan’s income is 25% more than Raman’s income i.e. x = y + 25% of y x = y + (25/100) y x = y (1 + (25/100)) x = y ((100 + 25)/100) x = y(125/100) Then, the difference between both the income is = (125/100)y – (25/100)y So, Raman’s income as compared to Mohan’s income, = (difference)/ (Mohan’s income) × 100 = ((25y/100)/(125y/100)) × 100 = (25/125) × 100 = 20%

(c) 20%

Let us assume Mohan’s income be ‘P’ and Raman’s income be ‘Q’

From the question it is given that,

Mohan’s income is 25% more than Raman’s income i.e. x = y + 25% of y

x = y + (25/100) y

x = y (1 + (25/100))

x = y ((100 + 25)/100)

x = y(125/100)

Then, the difference between both the income is = (125/100)y – (25/100)y

So,

Raman’s income as compared to Mohan’s income,

= (difference)/ (Mohan’s income) × 100

= ((25y/100)/(125y/100)) × 100

= (25/125) × 100

= 20%
