Question
18 workers can complete 9 tasks in 24 hours. Find the time
required by 12 workers to finish 15 tasks.Solution
ATQ,
Let the efficiency of each worker be 'x' tasks per hour
Let the required time be 't' hours
Therefore, (18x × 24) / 9 = (12x × t) / 15
Or, t = (18x × 24 × 15) / (12x × 9) = 60
Required time = 60 hours
Find the simplified value of the given expression.
(1/4) of {64Â - 28 x 15 + 13 x 16 - 12.5 of 122}
60 % of 640 - 57 × 2 - 1520 / 38 = ?
What will come in the place of question mark (?) in the given expression?
? = 70% of 36% of (25 × 320) + 150
- What will be come in place of (?) in the given expressions.
725 – [32 × 5 + {144 ÷ 12}] = ? 5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
- What will come in place of (?) in the given expression.
(625 ÷ 25) + (144 ÷ 12) – (81 ÷ 9) = ? 136% of 560 - 2/7 of 630 + 45% of 420 =?
What will come in place of the question mark (?) in the following question?
24.30% of 372.32 = ?
(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²
What will come in place of (?) in the given expression.
48 ÷ 4 + 6 × 3 - 5 = ?
