If a man rows at the rate of 19 kmph in still water and his rate against the current is 7 kmph, then find the man’s speed with downstream.
Rate in still water = 19 kmph Rate upstream = 7 kmph Rate of current = 19 – 7 = 12 kmph Rate downstream = 19 + 12 = 31 kmph
√784 × 3 + (713.99 ÷ 6.98) = ?% of 619.99
766/51 ÷ 387/42 × 121/13 = ?
648.13 ÷ 35.86 + 28.88 × 13.13 – 39.92% of 900.19 = ?
1359.98 ÷ 20.48 × 12.12 = ? × 4.16
? (30.03 - 17.98 × 15.99 ÷ 12.01) = 729.03
124% of 620.99 + 11.65% of 1279.23 = ?
480.11 ÷ 15.98 × 5.14 – 134.9 = √?
Solve the following expression and calculate the approximate value.
802 of
{44.78% of (11.67 × 54.78)} ÷ 2.65 = ? + 19.25
3.55% of 8120 – 66.66% of 540 = ? – 28% of 5500
