ANSWER

Let the no. of chocolates Rajesh got be x

∴ Total no. of chocolates =2x+1

Rajesh distributed his share equally among three of his friends and was also left with a chocolate.

∴(x−1) can be divided into 3 equal parts (assumed p)

∴x=3p+1 ....... (i)

As it is given that, one of the three distributed his share equally among four of his friends and was left with no chocolate.

∴p can be divided into 4 equal parts (assumed a)

∴p=4a

Substituting the value of p in eq (i), we get

x=3×4a+1

⇒x=12a+1

⇒(x−1)=12a ......... (ii)

∴(x−1) can be divided into 12 equal parts.

Therefore, 49 is the only value of x among given options which clearly defines equation (ii)
