SSC CGL 6th March 2020 Shift-2 Question 9

Question 9

The two given expressions on both the side of the ‘=’ sign will have the same value if two numbers from either side or both side are interchanged. Select the correct numbers to be interchanged from the given options.

$$4 + 6 \times 7 - 27 \div 3 = 7 \times 8 - 4 + 39 \div 3$$

Solution

$$4 + 6 \times 7 - 27 \div 3 = 7 \times 8 - 4 + 39 \div 3$$
After interchanged,
$$4 + 8 \times 7 - 27 \div 3 = 7 \times 6 - 4 + 39 \div 3$$
$$4 + 8 \times 7 - 9 = 7 \times 6 - 4 + 13$$
$$4 + 56 - 9 = 42 - 4 + 13$$
51 = 51
$$\therefore$$ The correct answer is option B.
