The answer is, 10
5) Answer: c)
The pattern is, ÷ 2 + 12, ÷ 2 +10, ÷ 2 + 8, ÷ 2 + 6, ÷ 2 + 4,…
The answer is, 32
Directions (Q. 6 – 10):
6) Answer: a)
Let the number of males and females who bought the books be x and y respectively,
Total number of peoples bought the books in Store T = 1200*(21/100) = 252
X + y = 252 –> (1)
X – y = 34 –> (2)
By solving the equation (1) and (2), we get,
X = 143, y = 109
The total number of females who bought the books in store T = 109
7) Answer: c)
The total number of people bought the books from shop A
= > 1200*(15/100)*(120/100) = 216
The total number of people bought the books from shop Q
= > 1200*(22/100) = 264
The total number of people bought the books from shop A and Q together
= > 216 + 264 = 480
8) Answer: b)
The central angle for the store Q
= > (22/100)*360 = 79.20
9) Answer: d)
In the month of Feb 2018, the total number of people bought the books from all the given book stores
= > 1200*(125/100) = 1500
The total number of people bought books in store P and S together in the month of Feb 2018
= > 1500*(33/100) = 495
10) Answer: a)
The average number of people bought the books from store Q and R together
= > 1200*(46/100)*(1/2) = 276
The average number of people bought the books from store S and T together
= > 1200*(36/100)*(1/2) = 216
Required difference = 276 – 216 = 60
