Question
Sachin Tendulkar's average runs over 40 innings was 52.
During his subsequent four innings, he scored 55, 42, 0, and 60 runs. To increase his average to 53 after the next inning, how many runs must he score?Solution
Sum of the runs scored by Sachin in 40 innings = 40 X 52 = 2,080 Sum of his score in next four innings = 55 + 42 + 0 + 60 = 157 So, required runs = 45 X (52 + 1) - 2,080 - 157 = 148
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
74.91% of 639.95 – 599.98% of 45 + 119.987 = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86

(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04Â
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
