Question
(5/9 of 2700.11) + (49.78% of 143.88) - (2/7 of 489.89)
= ? What approximate value should come in place of (?) in the following questions (Note: You are not expected to calculate the exact value.)Solution
(5/9 of 2700.11) + (49.78% of 143.88) - (2/7 of 489.89 (5/9 of 2700) + (50% of 144) - (2/7 of 490) 5/9 of 2700 = (5/9) × 2700 = 1500. 50% of 144 = (50/100) × 144 = 72. 2/7 of 490 = (2/7) × 490 = 140. Adding and subtracting: 1500 + 72 - 140 = 1432. Correct answer: b)
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long to row up as to row down the river. The rate of stream is:
