Question
Monthly savings of βQβ is 25% more than that of
βPβ and is 48% less than monthly income of βPβ. Monthly expenditure of βQβ is Rs. 3450 and ratio of monthly income of βPβ and βQβ is 10:19, respectively. Find monthly expenditure of βPβ.Solution
Let monthly income of βPβ and βQβ be Rs. β10xβ and Rs. β19xβ, respectively Monthly savings of βQβ = 52% Γ 10x = Rs. 5.2x Monthly savings of βPβ = {5.2/1.25} = Rs. 4.16x Monthly expenditure of βPβ = 10x β 4.16x = Rs. 5.84x Monthly expenditure of βQβ = 19x β 5.2x = Rs. 13.8x Or, 13.8x = 3450 Or, x = 3450/13.8 Or, x = 250 Monthly expenditure of βPβ = 5.84 Γ 250 = Rs. 1460
29% of 400 + 66% of 1100 - 50% of 1200 = ?Β
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
What will come in the place of question mark (?) in the given expression?
(17/27) of 162 + ?Β² = 632 - (73 - 12) X 5If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
β324 + β576 = ?/ β9
1/6+ 999*53/54Β Γ9Β = ?
22 + 60 Γ 3 Γ· 12 = ?
? = 60% of 2500 + 85% of 2000 β 5Β³
654.056 + 28.9015 Γ 44.851 β 43.129 = ?
4261 + 8234 + 2913 + 8217 + 6283 + 4172 =?
