Question
If Ankit takes four times the time that Ravi takes or five
times the time that Sandeep takes to finish a task, and all three working together can complete it in four days, how much time will Ravi need to complete the task alone?Solution
ATQ;
Let time taken by Ankit alone to finish the work = 20x
Time taken by Ravi alone to finish the work = 5x
Time taken by Sandeep alone to finish the work = 4x
Let total work = LCM of 20x, 5x, and 4x = 20x
Part of work done by Ankit, Ravi, and Sandeep alone in 1 day is 1 unit, 4 units, and 5 units respectively.
Total time taken to finish the task by all the 3 persons together = 4
20x / (1 + 4 + 5) = 4
x = 2
Time taken by Ravi alone to finish the work = 5x = 10 days
263 + 1152 - ? + 577 = 1333
√? = 32% of 900 + 48% of 50
What will come in the place of question mark (?) in the given expression?
?2 = 3945 ÷ 5 + 774 ÷ 6 – 77
If 1.123 × 3.211 = 3.122 + ______________, then the number in blank space is
Simplify the following expression:-
?2 = (1035 ÷ 23) × (1080 ÷ 24)
What will come in place of the question mark (?) in the following expression?
Simplify: 0.004 × 0.5
What will come in the place of question mark (?) in the given expression?
(? ÷ 16) = (20 ÷ ?) X 20Find the value of 45 - 3 x (4 of 6 + 12 ÷ 3 × 6 – 4 × 5) + 6.
