Question
Rajesh spent 30% and 24% of his monthly salary on food
and rent, respectively. Of the remaining amount, he gave 20% and 25% to his mother and brother, respectively. Find the amount spent by him on food, if the difference between the amount received by his brother and the amount spent on rent is Rs. 4500.Solution
Let the monthly salary of Rajesh be Rs. βxβ Amount spent on food = Rs. 0.30x Amount spent on rent = Rs. 0.24x Amount received by brother = (x - 0.30x - 0.24x) x 0.25 = 0.115x So according to question: 0.24x - 0.115x = 4500 0.125x = 4500 x = 36000 So, the amount spent on food = 0.30 x 36000 = Rs. 10800
?Β² = 37% of 800 β 14 Γ 18+ 5! - 20
If A = 0.84181818... then what will be the difference between the numerator and denominator of the lowest fraction form of A?
(144 ÷ 4)² × (72 ÷ 12)³ = 12 ×? × (25920 ÷10)
3/4 of 2000 + β1024 = ? + 12.5% of 3200
31% of 3300 +659 = ?
β? = 80% of 720 - 22% of 2500
25% of {(5/18) Γ 2880 + 122 } = ?% of 590
- What will come in place of (?), in the given expression.
75% of 640 β 20% of 150 = ? 1500 Γ 60% of 25% = ? 2Β
