a) Food = 20 % of expenditure => Amount spent on food = 20% of 50,000 = Rs. 10,000

b) Money spent on clothing and housing together = 25 % of Rs. 50,000 = Rs. 12,500 Money spent on transportation = 20 % of Rs. 50,000 = Rs. 10,000 Therefore, more money spent on clothing and housing together than on transportation = Rs. 12,500-10,000 = Rs. 2,500

c) Expenditure on food = 20 % Expenditure on education = 5 % Therefore, percent of amount on food spent as amount on education = (5 / 20) x 100 = 25 %

a) Central angle of A = Percentage of A x 360 degrees = (35 / 100) x 360 = 126 degrees

b) Sales of B = 20 % of 1200 = 240

c) Difference between the central angle of C and D = 40 % of 360 – 5 % of 360 = 35 % of 360 = 126 degrees

Let the missing number be ‘n’ 157.5 / 45 = 3.5 45 / 15 = 3 15 / n = 2.5 n / 3 = 2 3 / 2 = 1.5 2 / 2 = 1 Therefore, the missing number is 6

Let the missing number be ‘n’ 7 – 6 = 1 9 – 7 = 2 13 – 9 = 4 n – 13 = 8 Therefore, next number in the series = n = 21

1 x 1 + 2 = 3 3 x 2 + 4 = 10 10 x 3 + 6 = 36 36 x 4 + 8 = 152 152 x 5 + 10 = 770 770 x 6 + 12 = 4632 Therefore, the incorrect element in the series is 760.

If we consider statement 1 only, we can safely conclude that B is the tallest of all. If we consider statement 2 only, we can safely conclude that A is the shortest of all. Therefore, statement 1 alone is sufficient to answer the question
