# 3 Tricky Brain Teasers – Can You Solve?

Q1. Sameer purchased a mobile for \$600, sold it for \$800, bought it back again for \$900, and sold it again for \$1000. How much profit did he make?

Q2. If A x B = 2, C x D = 12, B x D = 3, and B x C = 4, what does A x B x C x D equal?

Q3. Two boys are writing an exam. They are identical. They have the same mother, father and birthday.

They were asked, “Are you twins?” they simply answer, “no, we are not”. How is this possible?

ANS 1 : Sameer had \$200 profit when he also for the first time then loss of \$100 while buying again then when he sold again he got a profit of \$100. Therefore total profit is \$200 – \$100 + \$100 = \$200.

ANS 2 : A × B ×C × D = 24

ANS 3 : They may be siblings born on same date & month but different year

AxD = 6 x BxC = 4, So AxBxCxD = 24

3. Both born on same date but in different years.
