A and B spend 60% and 75% of their incomes, respectively. If the savings of A are 20% more than that of B. then by what percentage is the income of A less than the income of B?
Answer & explanation
Correct answer: option 4
60% = \(\frac{3}{5}\) , 75% = \(\frac{3}{4}\) & 20% = \(\frac{1}{5}\)
Let the income of A = 100x & Income of B = 100y
ATQ,
\(\frac{2}{5}\)× 100x = \(\frac{1}{4}\) × \(\frac{6}{5}\) × 100y
40x = 30y
x : y = 3 : 4
Income of A is less than that of B by = \(\frac{(400-300)}{400}\) × 100
= 25%
