Question

In the following questions two equations I and II are given. You have to solve both the equations and give answer.

I. 2a + 3b = 31

II. 3a – 2b = 1

• A. if a b
• B. if a b
• C. if a b
• D. if a b

Answer 1

The correct option is A

if a b

2a + 3b = 31 .(i) 3a – 2b = 1.(ii) Multiply (i) by 2 and (ii) by 3 then adding (i) and (ii), we get $a=\frac{65}{13}=5$ Putting the value of `a' in any equation, We get b = 7. Hence b $>$a or a $<$ b.
