Question
Find the difference between the number of males and
number of females of tribe Raba. Answer the following questions based on the information given below: There are two tribes (Raba and Dimasa) in Mizoram. Total population of tribe Raba is 4800. Number of males of tribe Raba is 40% more than the number of females of tribe Raba. Total population of tribe Dimasa is 20% more than the population of tribe Raba. Ratio of number of males to the number of females of tribe Dimasa is 5:7.Solution
Let the number of females of tribe Raba be x. Number of males of tribe Raba = 1.4x Total population = 4800 => x + 1.4x = 4800 => x = 2000 Number of males of tribe Raba = 1.4 × 2000 = 2800 Number of females of tribe Raba = 2000 Total population of tribe Dimasa = 4800 × 1.2 = 5760 Number of males of tribe Dimasa = (5/12) × 5760 = 2400 Number of females of tribe Dimasa = (7/12) × 5760 = 3360 Required difference = 2800 – 2000 = 800
?% of 1499.89 + 54.14 × 8 = 25.05% of 5568.08
? = 41.92% of (34.92 x 40.42) + 29.78% of 399.84
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
? + 163.99 – 108.01 = 25.01 × 6.98
80.09 * √144.05+ ? * √224.87 = (2109.09 ÷ √1368.79) * 19.89
(15.15 ×  31.98) + 30.15% of 719.99 = ? + 124.34
(124.99)² = ?
6.992 + (2.01 × 2.98) + ? = 175.03
(627.98 ÷ 3.98 + 11.01 X 12.98 - ?) ÷ √623 = (178.98 + 37.08) ÷ 23.98Â
