Welcome to Online QuantTest in AffairsCloud.com. We are starting Cumulus Course for SBI PO 2019 Prelims Exam and we are creating sample questions in Quant section, this type of Question will be asked in SBI PO 2019.

This question contains two sub- questions i.e., Quantity 1 and Quantity 2. Quantity 1 will be the answer of the first question and Quantity 2 will be the answer of second question. Compare the two quantities – Quantity -1)Temple trust decides to build a worship hall having a carpet area of 300 square metres with its length one metre more than twice its breadth. What should be the breadth of the hall? Quantity- 2) There are two numbers whose sum is 27 and product is 182. Find the smaller number?

Correct

Answer -3. Quantity 1 < Quantity 2
Q1 = 12
Q2 = 13 Explanation –
Q1 = 12
Let the breadth of the hall = x
Length of the hall well be 2x+1
(2x+1).x = 300
2x^{2}+x = 300
2x^{2}+x-300 = 0
2x^{2}-24x+25x-300 = 0
2x(x-12) +25(x-12) = 0
X = 12, -12.5 (breadth cannot be negative)

Quantity 2= 13
Let the first number is x
Second number will be 27-x
X(27-x) = 182
X^{2} -27x+182 =0
X=13, 14

This consists of a question and two statements numbered 1 and 2 given below it. You have to decide if the data provided in the statements are sufficient to answer the question. Read both statements and mark answer. There are two bikes A and B which are 600km apart from each other. Find the distance between A and B at 11am.
Statement 1: Both the bikes started to move towards each other at 7am.
Statement 2: Speed of bike A is 40km/hr at 7am which decreases by 10% after every hour and speed of bike Q is 50km/ht at 7am which increases by 10% after every hour.

Correct

Answer -5) The data in both the statements 1 and 2 together are necessary to answer the question.
Explanation –
Statement 1 gives Direction in which bikes are moving.
Statement 2 gives Distance covered in that time.
Speed of bike A from 7am till 8am = 40km/hr
Speed of bike A from 8am till 9am = 40 × 9/10
Speed of bike A from 9am till 10am = 40 × 9/10 ×9/10
Speed of bike A from 10am till 11am = 40 × 9/10 ×9/10 × 9/10
Distance covered by bike A from 7am till 11am = 40[1+9/10 + (9/10)2 + (9/10)3] =137.56
Similarly, distance covered by bike B from 7am till 11am = 50[1 + 11/10 + (11/10)2 + (11/10)3] =232.05
Total distance covered till 11am = 137.56 + 232.05 = 369.61
Distance between A and B at 11am = 600-369.61 = 230.39

The above points are awarded by considering the following aspects given in pie chart.

What is the difference between total points achieved by K20 and P30 together in Durability to total points achieved by S10 and V15 together in Processor?

Correct

Answer – 1) 211.2
Explanation –
K20+P30 for Durability = 16% of (665+675) = 16% of 1340
S10+V15 for Processor = 32% of (685+645) = 32% of 1330
32% of 1330 – 16% of 1340
= 211.2

Incorrect

Answer – 1) 211.2
Explanation –
K20+P30 for Durability = 16% of (665+675) = 16% of 1340
S10+V15 for Processor = 32% of (685+645) = 32% of 1330
32% of 1330 – 16% of 1340
= 211.2
