- Arrange in ascending order- ¾, 5/12, 13/16, 16/29, 3/8.
Ans) 3/4 = 0.75
5/12 = 0.42
13/16 = 0.81
16/29 = 0.55
3/8 = 0.375
Therefore ascending order is :
3/8 < 5/12 < 16/29 < 3/4 < 13/16
- What is the average of all the prime numbers between 30 and 50?(35.857)
Ans) There are five prime numbers between 30 and 50.
They are 31,37,41,43 and 47.
Therefore,
the required average = (31+37+41+43+47)/5 = 199/5 = 39.8
- If population of a town increases by 44% in first year and 75% in second year, what is the average rate of increase of population? (76%)
Ans) Let population of town initially =100X
Population after 44% increase in 1st year = 100X + 44 /100 × 100X = 144X
Population after 75% increase in 2nd year = 144X + 75/100 x 144X = 252X
Thus, rate of increase in population
= {(252X – 144X)/100X} x 100 = 152%
=> Average rate of increase in population in 2 years = 152/2 = 76%
- Sum of Rs 2000 becomes Rs 3645 in 2 years on compound interest. What will be the sum after 4 years on the same rate of compound interest? ( Rs 6643.0125)
Ans) When the interest is compounded annually,
Amount after n years = Principal × (1 + Rate/100)^n
Given, Principal = Rs. 2000
Amount after 2 years = Rs. 3645
=> 3645 = 2000 × (1 + Rate/100)^2
=> (1 + Rate/100)^2 = 3645/2000 = 729/400
Now,
Amount after 4 years = 2000 × (1 + Rate/100)^4 = 2000 × (1 + Rate/100)^2 × (1 + Rate/100)^2
Therefore,
Amount after 4 years = 3645 × 729/400 = Rs. 6643.0125
