Question
The university has 750 faculty (male and female only)
out of which the females are 60%. The average height of females is 162 cm and that of males is 168 cm. What is the average height of the faculty (in cm) of the university?Solution
Total faculty: 750 Percentage of females: 60% Number of females = 60 /100 x 750 =450 Number of males = 750-450 = 300 Average height of females = 162 cm Average height of males = 168 cm The average height of all faculty members: Average height = [(450x162) + (300 × 168)]/ 750 = [72900+50400]/750 =123300/750 =164.4cm.
20% of 1500 – 75% of 200 = 125% of ?Â
24% of 150% of 500 + 140 = ? × 8Â
458.32 - 563.32 + 659.32 =?
What will come in the place of question mark (?) in the given expression?
(√1089 + 84 ÷ 2) % of 348 = 416 - ?

40% are the passing marks. A student gets 250 marks yet fails by 38 marks. What is the maximum marks?
(22.5 × 24) ÷ 40 + 51.50 = ? ÷ 5.25
36×?² + (25% of 208 +13) = 60% of 2400 + 17×18
What will come in the place of question mark (?) in the given expression?
√64 X 9 ÷ 3 + 12 X 3 = ? + 36(3/7) x 868 + 25% of 240 = (? + 65)
