B: means ‘x3’
C: means ‘-3’
D: means ‘+3’
E: means ‘÷2’
F: means ‘x2’
G: means ‘-2’
H: means ‘+2’
Solution
Expression : 18x3 ÷2+3 <27 ?
L.H.S = 18x3 ÷2+3
= $$\frac{54}{2}+3 = 30$$
Now, R.H.S. should be greater than 30
R.H.S. = 27 ?
(A) : D followed by A
= $$27+3 \div 3 = 27+1=28$$
(B) : A followed by G
= $$27 \div 3-2 = 9-2=7$$
(C) : D followed by G
= $$27+3-2=28$$
(D) : D followed by H
= $$27+3+2=32$$
=> Ans - (D)
