Question 29

If ‘P’ means ‘+’, ‘Q’ means ‘-’, ‘R’ means ‘÷’ and ‘S’ means ‘x’, then which of the following equation is correct?

Solution

Given : ‘P’ means ‘+’, ‘Q’ means ‘-’, ‘R’ means ‘÷’ and ‘S’ means ‘x’

(A) : 14 R 7 S 6 P 4 Q 3 = 11

L.H.S. = $$14\div7\times6+4-3$$

= $$12+1=13\neq$$ R.H.S.

(B) : 3 S 6 P 2 Q 3 R 6 = 35/2

L.H.S. = $$3\times6+2-3\div6$$

= $$18+2-0.5=19.5=\frac{39}{2}\neq$$ R.H.S.

(C) : 11 R 12 S 48 P 10 Q 6 = 48

L.H.S. = $$11\div12\times48+10-6$$

= $$44+4=48=$$ R.H.S.

=> Ans - (C)
