Question
If 'p' is subtracted from 18, 24,
16, and 12, the resulting numbers will be in proportion. Find the value of 'p'.Solution
ATQ, (18-p)/(24-p) = (16-p)/(12-p) Or, (18 - p )(12 - p) = (16 - p)(24 - p) Or, 216 - 18p - 12p + p2 = 384 - 16p - 24p + p2 Or, 216 - 30p = 384 - 40p Or, 216 - 384 = - 40p + 30p Or, 10p = 168 Or, p = 16.8
?% of (168 ÷ 8 × 20) = 126
20% of 1500 – 75% of 200 = 125% of ?
Find the value of 16 X [(8 - 5) of 12 ÷ 4].
√196 + (0.25 × 144) + 19 = ? + 72
22 * 6 + 45% of 90 + 65% of 180 = ?
52% of 400 + √(?) = 60% of 600 - 25% of 400
(25 × 12 + 30 × 8 – 22 × 10) = ?
What will come in the place of question mark (?) in the given expression?
(240% of 175 ÷ √16) X 6 + 80% of 400 = ?3 + 179 + 42
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
808 ÷ (128)1/7 + 482 = 4 × ? + 846
