Key Answers to Numerical Reasoning Questions in 2017 CSE:

116. (2) next number in the sequence is 3. Notice that the numbers in the pattern were divided by 3 to get the next number. Therefore, you divide 2187 by 3 you’ll get 729, then the next and so on.
117. (3) 81 – you can get this by squaring the numbers (1×1=1), (2×2=4), (3×3=9) and so on…
118. (4) -144 – subtract the 3rd and 1st to get the 2nd number, do the same to the next 3 sets
119. (1) IR KP – Use the equivalent ascending and descending letters in the alphabet
120. (2) P15625 – the pattern is the next 2 letters from the alphabet and the number multiplied by 5 to get the next one…
121. (2) -9 –positive + negative numbers is to subtract them and follow the sign of the bigger number
122. (3) 124 – positive – negative numbers is to change the sign of the subtrahend and follow the rules in addition
123. (1) 198 – multiplying numbers with similar signs = positive
124. (1) -100 – already explained
125. (1) -80 – dividing numbers with different signs = negative
126. (4) ¾ + 5/2 + 1/3 – simplify the fractions given and convert the mixed number into improper fraction
127. (3) LCD is 16 – the denominators are: 8, 4 and 16
128. (3) GCF is 18 since 36 and 64 are divisible by 18, 9, 6, 3
129. (3) the answer is 3 because ½ + 2 + ½ = 3
130. (2) the answer is 6/27 simplified into 2/9
131. a. Find the rate at which Susan is traveling by dividing her distance by time; 114 ÷ 2 = 57 mph. To find out how long it will take her to travel 285 miles, divide her distance by her rate; 285 ÷ 57 = 5 hours.
132. d. Divide the miles by the time to find the rate; 3,060 ÷ 5 = 612 mph.
133. c. He spent $72 on pants (3 × $24 = $72) and $90 on shirts (5 × $18 = $90). Altogether he spent
$162 ($72 + $90 = $162). If you chose a, you calculated the cost of ONE pair of pants plus ONE shirt instead of THREE pants and FIVE shirts.
134. b. There are 100 cm in a meter. A square meter is 100 cm by 100 cm. The area of this is 10,000 sq cm (100 × 100 = 10,000).
135. a. There are 36 inches in a yard; 4 × 36 = 144 inches. There are 144 inches in 4 yards.
