Question
Employee P manufactures 24 bottles an hour, and Employee Q
manufactures 16 bottles per hour. If 20% of the bottles are damaged, how much time is required to produce 320 good bottles?Solution
ATQ,
(To make 320 good bottles, they need to make:
320 ÷ 0.8 = 400 bottles in total
Time taken to make 400 bottles = 400 ÷ (24 + 16) = 400 ÷ 40 = 10 hours

280 – 70 × 14 ÷ 5 = ? – 21 of 3
- What will come in place of (?) in the given expression.
(18.5 × 2) + (3.5 × 4) = ? 4.5 times 5/0.9× 35% of 240 =?
144% of 200 + 11% of 900 + 10% of 20 =?
Find the value of 'p' in the given expression: 15 of 6 ÷ p x 4 = 30.
300% of (3341 – 471) = ? × (√4225/195)
What will come in the place of question mark (?) in the given expression?
? = (27 × 13) – 26% of (412 – 92 )
What will come in the place of question mark (?) in the given expression?
(87 + 79) X √9 - 298 = ? + √3600
(1/5){(2/5) × 400 + 20% of 150} = ?Â
