Question
Archana's income is 40% higher than Bhasker's, and
Cherry's income is 60% more than Bhasker's. Both Archana and Cherry save Rs. 8,000 each, with the expenditure ratio of Archana to Cherry being 6:7. Determine the percentage of his income that Bhasker spends.Solution
ATQ, Let, the income of 'Bhashker' be Rs.'5x'. So, the income of 'Archana' = 1.4 × 5x = Rs.'7x' Income of 'C' = 1.6 × 5x = Rs. '8x' Let, the expenditure of 'Archana' and 'Cherry' be Rs.'6y' and Rs.'7y', respectively. ATQ, 7x - 6y = 8000 ....(i) 8x - 7y = 8000 On comparing the above two equations, we get, 7x - 6y = 8x - 7y Or, 8x - 7x = 7y - 6y So, x = y ....(ii) From equation (i) and (ii) , we get, 7x - 6x = 8000 So, x = 8000 So, the income of 'Bhasker' = 5x = 5 X 8000 = Rs. 40,000 Expenditure of'Bhasker' = 40000 - 8000 = Rs. 32,000 So, the percentage expenditure of 'Bhasker' = (32000/40000) × 100 = 80%
961 × 4 ÷ 31 – 15% of 180 = ? – 73
1 + 1 + 1/2+ 1/3 + 1/6 + 1/4 is equal to ____
(225 + 125) ÷ 7 + 250 = ? + 20% of 800
128 ÷ 22 × ? = 15% of 300 ÷ 9
22.5% of 300 + 32.5% of 4500 =?
{(5/8) + (4/5)} × (?/19) = 33
1555.5 + 1000.8 – 1354.3 = ? + 52
(1520 - 1350) ÷ (550 – 500) = ?
108² + 99 X 98² =?
...[(11)2 - (12)2 + (5)3]2 = ?
