GENERAL INTELLIGENCE & REASONING

If "P” denotes “multiplied by", “Q" denotes “subtracted from”, “S” denotes “added to” and “R” denotes “divided by”, then which of the following equation must be true?

7 S 56 P 2 R 28 = 11
36 R 6 P 2 S 4 = 19
64 R 8 P 3 S 6 = 72
36 R 9 S 4 P 2 = 14

Solution:

Concept:

Replace each letter with its given arithmetic operator, then evaluate using BODMAS.

Explanation:

Given:

P=\times

,

Q=-

,

S=+

,

R=\div

.

Check option A:

7\,S\,56\,P\,2\,R\,28=11

becomes

7+56\times2\div28=11

.

First solve

56\times2=112

.

Then

112\div28=4

.

Finally

7+4=11

, so option A is true.

Check other options:

B:

36\div6\times2+4=16\neq19

.

C:

64\div8\times3+6=30\neq72

.

D:

36\div9+4\times2=12\neq14

.

Thus only option A satisfies the condition.

Answer:

Option A:

7\,S\,56\,P\,2\,R\,28=11

is correct.
