Question
Ayaan and Kabir started working together on a task. Ayaan
does 4 units per day and Kabir can finish the full task in 25 days alone. The total work is 100 units. Calculate the time taken by both working together.Solution
ATQ,
Let, the time taken by Ayaan and Kabir to do the work be ‘x’ days.
Units of work done by Kabir in a day = 100 / 25 = 4 units
So, 100 / x = 4 + 4 = 8
100 = 8x
x = 100 / 8 or 25/2
Find the value of ?
{[(864 ÷ 18) ÷ 8] ÷ 3} + 11² – 2³ = ?
What will come in the place of question mark (?) in the given expression?
(√? - 17) X 40 + 145 = 1000 - 15Â
3 √8 × √36 × 13 = ? × √169
What will come in the place of question mark (?) in the given expression?
? = 70% of 36% of (25 × 320) + 150
Find the simplified value of the following expression:
72Â + 132Â X 4 - {232Â + 172Â - 402
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
17% of 250 + ? = 108
3(2/5) + 6(1/3) + 3(2/5) + 11(2/3) =?
12(3/5) + 4(1/5) × 3(2/3) =?
What will come in the place of question mark (?) in the given expression?
133 ÷ 19 X √576 + ? ÷ 2 = 32 X 7.5
