Question
The ratio of income and expenditure of a man is 5 : 3,
respectively. If the income and expenditure of the man are increased by 20% and 25% respectively, then find the percentage increase in the savings of the man.Solution
Let the income of the man be Rs. β5xβ So, expenditure of the man = Rs. β3xβ So, savings of the man = 5x β 3x = Rs. β2xβ New income of the man = 5x Γ 1.2 = Rs. β6xβ So, new expenditure of the man = 3x Γ 1.25 = Rs. β3.75xβ So, new saving = 6x β 3.75x = Rs. β2.25xβ So, required percentage increase
= {(2.25x β 2x) / 2x} Γ 100
= 12.5%

β196 + (0.25 Γ 144) + 19 = ? + 72
20% of 240 + 18% of 200 = ?
(1/3) + (2/5) + (3/4) + (11/10) = 3 β (?/12)
What will come in place of (?) in the given expression.
(3/4 of 64) + (1/2 of 48) = ?30% of 180 + 248 Γ· ? - β256 = 102
[{(1296 Γ· 18) Γ· 12} Γ· 6] + 82 + β625 = ?
25% of {(5/18) Γ 2880 + 122 } = ?% of 590
Simplify and express as a fraction in simplest form:
0.75 + 0.4 β 0.125
Β β256 * 4 β 30% of 190 + ? = 110% of 220
