14. Two goats are tied with a rope of length 40m outside of a rectangular shed of dimensions 50m X 30m. The goats are tied to different corners which lie on the opposite ends of a diagonal of the shed. What is the area in which the two goats can eat grass, if they choose not to eat in the common approachable area?
A) 1200Ï€

B) 1225Ï€

C) 2400Ï€

D) 2450Ï€
[Ans: D It is clear that 3/4th of the circle (radius 40m) is covered by each goat. So 2 goats * (area of 3 quadrants for each goat) = 2* 1200 = 2400(pie) square units As the goats do not eat in the common area the radius becomes 10m for the fourth quadrant for each goat hence (2 goats)*(area of quad. for each goat) = 2*(3.14*10*10*(1/4)) = 50pie square units hence total area is (2400+50) pie = 2450pie square units.]

20. If 105 is represented as 253 in base 6, how is 253 represented in base 6?
[Ans: 1101 253%6 = 1 (Quotient = 42). 42%6 = 0 (Quotient = 7). 7%6 = 1 (Quotient = 1). 1%6 = 1 (Quotient = 1) Now write in reverse order = 1101]

21. Mr Roy found an old bill which shows that he brought 10 hens for Rs_ 67.92_ ,the first and the last digits were missing. What was the cost of each hen?
[Ans: Data insufficient. The first digit ranges from 1 to 9. The last digit also ranges from 1 to 9. So, approximately the total cost for 10 hens might be 168 to 968. So, we can say that cost of each hen might be 16.80 to 96.80 or 17 to 97 approx]

[Ans: Let x = population number After 1 year population = x*1.04 After 2 years population = x*1.04*1.04*1.04 = x*1.04^3 = x*1.124864 So after 2 years the population has increases by (1-1.124864)*100 percent or 12.48% ]

23. The ratio of the number of boys and girls in a school is 3:2 Out of these 10% the boys and 25% of girls are scholarship holders. What is the percentage of students who are not scholarship holders?
