Question
Income of 'A' is Rs. 1,600 more than that of 'B'. Both
spend 40% of their respective incomes. If the savings of 'C' is 25% of his income and equals the difference between the savings of 'A' and 'B', find income of 'C'.Solution
Let the income of 'A' be Rs. 'x' Income of 'B' = Rs. (x β 1600) Difference between savings
= 0.60x β 0.60(x β 1600)
= 0.60x β 0.60x + 0.60 Γ 1600
= Rs. 960 Therefore, income of 'C' = (960/0.25) = Rs. 3,840

300β40%Β ofΒ 200=? - Simplify the following expression:
16 + [17 - (8 + 11) + 6 - 3] Γ· 0.2 Simplify the following expression.
(3-3 Γ 3 + 3 Γ· 3 + 3 Γ 5) Γ 2 of 5 + (2 + 2 Γ· 2 + 2 Γ 2 - 2)
2/9 of 5/8 of 3/25 of ? = 40
115 Γ· 23 + 12 Γ 6 = ? + 16 - 35
β? = 32% of 900 + 48% of 50

5/13 Γ 104 + 1(2/9) Γ 198 = 133 + ?
Simplify the following expressions and choose the correct option.
40% of 360 + 25% of 248 - 30
(11/12) Γ (18/22) Γ (4/3) + 3 = ?2
[(15)³ × (8)²] ÷ (90 × 6) = ?²
