Question
In 2023, if all teams worked together to complete a
project that requires 500 total worker-days, how many days would they take to complete the project? A construction company has five teams (A, B, C, D, E) working on different projects. The table below shows the number of workers in each team and the number of days they took to complete their respective projects over three years.Solution
In 2023, the number of workers in each team: Team A = 70 workers Team B = 80 workers Team C = 65 workers Team D = 75 workers Team E = 60 workers Total workers in 2023 = 70 + 80 + 65 + 75 + 60 = 350 workers. Total worker-days required for the project = 500 worker-days. Time taken by the combined workforce to complete the project: Days = Total worker-days / Total workers = 500 / 350 = 1.43 days. Ans. d
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}
