Question
The average weight of 4 persons is 38 kg. The heaviest
person’s weight is 22 kg more than the lightest person’s weight. If the average weight of the rest two persons is 42 kg, then find the weight of the heaviest person.Solution
The sum of the weight of 4 persons = 38 × 4 = 152 kg Let the weight of the lightest person = ‘x’ kg The weight of the heaviest person = (x + 22) kg The sum of the weight of the remaining two persons = 42 × 2 = 84 kg According to the question, x + x + 22 + 84 = 152 2x = 46 x = 23 The weight of the heaviest person = 23 + 22 = 45 kg
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
