Question 29

By interchanging which two signs the equation will be correct?
19 + 36 x 12 ÷ 4 - 26 = 5

Solution

Expression : 19 + 36 x 12 ÷ 4 - 26 = 5

(A) : + and -

$$\equiv19-36\times12\div4+26=5$$

L.H.S. = $$19-(36\times3)+26=19-108+26=-63\neq$$ R.H.S.

(B) : x and ÷

$$\equiv19+36\div12\times4-26=5$$

L.H.S. = $$19+(3\times4)-26=19+12-26=5=$$ R.H.S.

=> Ans - (B)
