Question 18

Which of the following interchanges in signs and numbers will make the given equation correct?
8 x 6 + 4 = 52

Solution

Expression : 8 x 6 + 4 = 52

(A) : x and +, 8 and 52

$$\equiv52+6\times4=8$$

L.H.S. $$=52+24=76\neq$$ R.H.S.

(B) : + and x, 6 and 4

$$\equiv8+4\times6=52$$

L.H.S. $$=8+24=32\neq$$ R.H.S.

(C) : x and +, 8 and 4

$$\equiv4+6\times8=52$$

L.H.S. $$=4+48=52=$$ R.H.S.

=> Ans - (C)
