Q4. Which one of the four interchanges in signs and numbers would make the given equation correct? 
3 + 5 – 2 = 4
चिन्हों और संख्याओं के दिए गए चार बदलाव में कौन सा बदलाव समीकरण को सही बनाएगा? 
3 + 5 – 2 = 4   
(a) + and -, 2 and 3
(b) + and -, 2 and 5
(c) + and -, 3 and 5
(d) None of these


S4. Ans.(c)
Sol.
By making the interchanges given in (a), we get the question as 2 – 5 + 3 = 4 or 0 = 4, which is false.
By making the interchanges given in (b), we get the equation as 3 – 2 + 5 = 4 or 6 = 4, which is false.
By making the interchanges given in (c), we get the equation as 5 – 3 + 2 = 4 or 4 = 4, which is true.
So, the answer is (c).
