SSC CHSL Maths Questions
We have provided some examples of the SSC CHSL Maths Questions and Answers that are frequently asked in the tier 1 exam. In addition to that, we have also shared detailed solutions to each question to understand the right approach to solving SSC CHSL Maths Questions in the upcoming exam.
1. The LCM of two numbers is 2900% more than their HCF and sum of LCM and HCF of the two numbers is 310. If one of the number is 20, find the other number.
A. 290
B. 150
C. 75
D. 300
Given, LCM + HCF = 310
30x + x = 310
x = 10
Hence, LCM = 300 & HCF = 10
Now, LCM × HCF = N_{1} × N_{2}
300 × 10 = 20 × N_{2}
N_{2} = 150
2. Find the smallest number of 4 digits which is always divisible by 12, 18, 30 and 45 when it is increased by 8.
A. 1072
B. 1080
C. 1088
D. 1096
LCM (12, 18, 30, 45) = 180
Smallest 4 digit multiple = 1080
So, the number is 1080 – 8 = 1072
3. Find the least number which must be subtracted from 2423 so that the resultant number when divided by 15, 25 and 40 leaves remainder of 7 in each case.
A. 8
B. 12
C. 16
D. 20
4. There are three classes A, B and C with 72, 96 and 144 students respectively. Find the minimum number of small groups in which they can be divided such that each group has students from one class only and each small group has equal number of students.
A. 9
B. 10
C. 11
D. 13
5. Four different electronic devices make a beep after every 30 minutes, 1 hour, 1 hour 30 minutes and 1 hour 45 minutes respectively. All the device beeped together a.m. 12 noon. They will again beep together at:
A. 12 midnight

A. ₹ 6
B. ₹ 20
C. ₹ 34
D. ₹ 75
7. If the ∆ABC is right angled at B, find its circumradius if the sides AB and BC are 15 cm and 20 cm respectively.
A. 25 cm
B. 20 cm
C. 15 cm
D. 12.5 cm
8. If a shirt costs ₹ 64, after 20% discount is allowed, what was its original price in ₹?
A. 76.80
B. 80
C. 86
D. 86.80
9. A trader allows a discount of 10% on the marked price. He still has a profit of 17% on the cost price. Find the profit % if he sells at the marked price?
A. 27%
B. 33%
C. 30%
D. 19%
Short trick:
Let the CP be Rs. 100 and MP be Rs.x
According to question:
90% of x = 117
x = 130
Required profit % = 30%
10. If A = (2/3) of B and B = (4/5) of C, then A : B : C is:
A. 12 : 8 : 10
B. 15 : 10 : 8
