Question
Anil spends 20% of the monthly income on the
reconstruction of his house, 15% on basic needs, 10% of the remaining on travelling. If he spends (100/9)% of the remaining income on food and he saves Rs.7280, then find the monthly income of Anil.Solution
Let monthly income of Anil = Rs. 100x Amount spend on reconstruction and on basic needs = 100x × [(20 + 15)/100] = 35x Amount spend on travelling = (100x – 35x) × (10/100) = 6.5x Amount spend on food = (100x – 35x – 6.5x) × (1/9) = 6.5x According to the question, => 100x – 35x – 6.5x – 6.5x = 7280 => x = 140 Therefore, his monthly income = 100 × 140 = Rs.14000
Simplify the expression:
(4x² - 16) / (2x - 4)
139 + 323 – √169 + ? = 450
9999² + 1111² =?
20% of 240 + 18% of 200 = ?
4(1/3) × 2(11/14) = 50% of ? + 86/11
- What will come in place of (?), in the given expression.
√2025 + 35% of 400 = ? Find the value of the expression:
18 + 12 – 4 × [22 + 6 – 2 × (38 – 23)]Simplify the following questions:
(11) 8.5 × (121) 5.5 ÷ (1331) 5.5 = (11) ?
...135 ÷ 3 of 5 = ? - 112
What will come in the place of question mark (?) in the given expression?
412 + 25% of 2400 = ? + 1131
