Question
'S' earns 50% more than 'T'. 'S' and 'T' save 45% and
25% of their incomes. If the gap between their expenses is Rs. 1,200, how much does 'S' save?Solution
ATQ,
Let the income of 'T' be Rs. '100n'
Income of 'S' = 1.5 Γ 100n = Rs. '150n'
Expenditure of 'S' = 0.55 Γ 150n = Rs. '82.5n'
Expenditure of 'T' = 0.75 Γ 100n = Rs. '75n'
So, 82.5n - 75n = 1200
Or, 7.5n = 1200
Or, 'n' = 160
Savings of 'S' = 150n - 82.5n = 67.5n = 67.5 Γ 160 = Rs. 10,800
1500 Γ 60% of 25% = ? 2Β
What will come in the place of question mark (?) in the given expression?
{122 + (66/4) + (252/8)} Γ· 8 = (?)1/2
2 X 25 + (30% of 80) Γ· (10% of 120) = ?
289 + 896 + 144 β 25% of 1100 =?
Find the value of the expression:
18 + 12 β 4 Γ [22 + 6 β 2 Γ (38 β 23)]{640 of 8 - (12)2 of 6} - 900 = ?
What will come in place of (?) in the given expression.
β625 + 12 Γ 5 = ?666(2/3)% of 30 - 116(2/3)% of 90 =?
What will come in the place of question mark (?) in the given expression?
40% of 150 - ?% of 75 = 15 Γ 1.6
6 × 5.5 + 4.5 × 20 - 102 = ?
