Question
The monthly income of a person is Rs.25000 from which
he spends 20% on rent, 10% of remaining on food and 20% of remaining on clothing. The remaining amount, he shares between his son and daughter in the ratio of 5:4. Find the difference between amount spent on rent and share of his daughter.Solution
Let monthly income be 100x. Spent on rent = 100x × (20/100) = 20x Spent on food = (100x − 20x) × (10/100) = 8x Spent on clothing = (100x − 20x − 8x) × (20/100) = 14.4x Remaining amount = 100x − 20x − 8x − 14.4x = 57.6x Share of son = 57.6x × (5/9) = 32x Share of daughter = 57.6x − 32x = 25.6x Required difference = 25.6x − 20x = 5.6x => 5.6x × (25000/100x) = Rs. 1400

Solve the given equation for ?. Find the approximate value.
(3/5 of 399.78 + 7/9 of 360.15) ÷ (√63.94 + 25% of 383.94) = ?
...[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
65.22 of 359.98% + 459.99 ÷ 23.18 = ?
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
