Question
The income of Suresh is 30% higher than that of Mukesh.
While Mukesh spends 80% of his income, Suresh spends 60% of his income. If Suresh saves Rs. 6,500, what is the amount saved by Mukesh?Solution
Let income of Mukesh be Rs. '100m' Income of Suresh = 1.3 X 100m = Rs. '130m' Expenditure of Mukesh = 0.8 X 100m = Rs. 80m Expenditure of Suresh = 0.6 X 130m = '78m' Savings of Suresh = 130m - 78m = 52m So, 52m = 6,500 Or, 'm' = 125 Therefore, savings of Mukesh = 100m - 80m = 20 X 125 = Rs. 2,500
68.98 × 41.03 – (12.33)² + 15.78% of 8398.87 = ? – 40.22

Find the approximate value of Question mark(?). No need to find the exact value.
(55.96 × 4.01) ÷ 7 + √(120.81) × 3 – 10% of 199.99 = ?<...
? = 782.24 + 1276.97 – 4.992
431.98 + ? – 15.04 = 864.93 – 368.01
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
40.024 of 54.89% of 19.9 = ? × √(2661.98/22.09)
13.002 × 34.995 + 499.996% of 100.08 + 25.005 % of 3999.997 = ? × 8.908 × 5.909
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
(44/25) ÷ (154/199.5) × 419.91 = ? – (11.11)3
