Question
The income of a person is Rs.10000 and his expenditure
is Rs.8000. In the next year his income and expenditure is increased by 8% and 12% respectively. His saving is what percent less than that of the previous saving?Solution
Initial Savings = 10000 – 8000 = Rs. 2000 Next year, Income = 10000 × (108/100) = Rs.10800 Expenditure = 8000 × (112/100) = Rs.8960 Saving = 10800 – 8960 = Rs.1840 Required % = [(2000 – 1840)/2000] × 100 = 8%
14.99% of 7820 + 5535.25 ÷ 123.001 - ? = 84
18.22 × 11.99 + 154.15 = ?
 (3/5) of 3025 + (18² + 12²) = ? + 22.22% of 1125
5.25 x 4.09 + 3.99 x 9.67 + 6.01 x 14.88 = ?
? = 16.08 + 13.99 × 25.07
20.99 × √4.09 × 30.09 = ? × √195.99 × 15.09
1279.98 ÷ 40.48 × 10.12 = ? × 2.16
30.01 × √1023 + 196 = ? 2 – 287
?% of (150.31 ÷ 14.97 × 50.011) = 319.98
