Question
Amit and Bheem can individually
finish a task in 10 days and 15 days, respectively. If they work together to complete the task and earn a total payment of Rs. 600, how much of the payment does Amit receive?Solution
ATQ, Let total task = 30 units {LCM of 10 and 15} Efficiency of 'Amit' = 3 units per day Efficiency of 'Bheem' = 2 units per day Since, they completed the whole task together therefore ratio of wage received by them will be same as the ratio of their efficiencies. So, required wage received by 'Amit' = {3/(3 + 2)} × 600 = Rs. 360
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
