In the following question, by using which mathematical operators will the expression become correct?

Question 26

69 ? 3 ? 2 ? 9 ? 3

Solution

Expression = 69 ? 3 ? 2 ? 9 ? 3

(A) ÷, -, > and ×

$$\equiv69\div3-2>9\times3$$

L.H.S. = $$\frac{69}{3}-2=21$$

R.H.S. = $$9\times3=27$$

But L.H.S. < R.H.S.

(B) ÷, +, < and ×

$$\equiv69\div3+2<9\times3$$

L.H.S. = $$\frac{69}{3}+2=25$$

R.H.S. = $$9\times3=27$$

It is correct because L.H.S. < R.H.S.

=> Ans - (B)
