mathematical operation Model Questions & Answers, Practice Test for ssc mts paper 1 2023

Answer: (b)

Using the proper notations in (c), we get the statement as

5 × 2 ÷ 2 < 10 – 4 + 8 or 5 × 1 < 18 – 4 or 5 < 14, which is true.

Answer: (d)

A + D > C + E

⇒ A + D > (2B – D) + E (∵ C + D = 2B)

⇒ A + D > (B + E) + (B – D)

⇒ A + D > (C + D) + (B – D)

⇒ A + D > B + C.

Answer: (a)

Using the correct symbols, we have

Given expression = (3 × 15 + 19) ÷ 8 – 6

= 64 ÷ 8 – 6 = 8 – 6 = 2.

Answer: (c)

Using the proper signs in the given expression , we get

175 ÷ 5 × 20 – 3 × 10 = 7 + 5 x 20 – 3 × 10

= 7 + 100 – 30 = 107 – 30 = 77.

Answer: (d)

Given A + B = C + D

⇒ A – D = C – B .............(1)

and A + D > B + C .............(2)

Subtracting (1) from (2) we get 2D > 2B or D > B.

hence B > D is a wrong statement ,
