Question
A fan manufacturer found that 27% of the total product
is defective. If the number of products in good condition is 4088 then find out the number of defective products.Solution
ATQ, Let the total number of products be N. If 23% are defective the remaining are in good condition Hence 73% of N = 4088 N = 4088/73 ×100 = 5600 number of defective products = 5600-4088 = 1512
√729 × 5 + 270 - 3 ÷ ∛27 + 4 × ? = 484

...What will come in the place of question mark (?) in the given expression?
65% of 900 - 45% of 600 = ? X 3Â
Simplify the following expressions and choose the correct option.
(72 ÷ 3) × (5/6) + 7² = ?
?% of 740 – 8% of 650 = 7.2
- Find the simplified value of the given expression.

What will come in the place of question mark (?) in the given expression?
{(2/15) + (12/25)} of 375 + 190 = ?% of 375
(3984 ÷ 24) x (5862 ÷ 40) = ?
What will come in the place of question mark (?) in the given expression?
(72 × 6 ÷ 12) × 6 = ?
What value should come in the place of (?) in the following questions?
√16 * ? = √144 + (18 * 4 ÷ 3)
