Question
In an office, the average weight of women is 34 kg and
the average weight of men is 30 kg. If the number of women is three times the number of men, what will be the average weight of all the employees in the office?Solution
ATQ,
Let the number of men be 'm' Therefore, number of women = '3m' So, ATQ, Required average = (34×3m+30×m)/(3m+m) = 132m/4m = 33 kg
63.89% of 549.68 – (739.87 ÷ 5.34) = ? × 11.89
(? + 6.063.03 ) ÷ 10.08 + 21.89 × 6.97 = 1979.97 ÷ 10.96
17.06 2 + √36.08 – (4.04/2.99) × 3.02 × 4.92 = ? × 4.99
20.22% of (74.9 × 6.01) + 69.97 =?
16.98 × 88.05 + 1999.996% of 299.08 + 5.005 % of 4999.997 = ? × 20.98 × 40.009
? = 65.78² ÷ (5.01⁵ + 7.02 × 33.33) + 33.33% of (290.88 × 23.09)
( 22.01% of 899.80 ) × 15.99 = ? 2 + 27.98 × 2400 ÷ 800
11.232 + 29.98% of 599.99 = ? × 6.99
Find the approximate value of Question mark(?). There is no requirement to find the exact value.
? = 599.77 – 14.08 × 20.11 + (12.93)²
63.95 – 21.12 – 24.89 + 6.04 = 3.98 × ? + 3.88
