Solve : $$1\frac{1}{2}$$ + $$2\frac{2}{7}$$ = $$3\frac{1}{2}$$ + ?

A. $$\frac{2}{3}$$

B. $$\frac{2}{7}$$

C. $$\frac{5}{8}$$

D. $$\frac{7}{2}$$

E. $$\frac{1}{7}$$

Answer: Option B

Solution(By Examveda Team)

Let the missing number be x
Given, $$1\frac{1}{2}$$ + $$2\frac{2}{7}$$ = $$3\frac{1}{2}$$ + x
x = $$1\frac{1}{2}$$ + $$2\frac{2}{7}$$ - $$3\frac{1}{2}$$
x = $$\frac{3}{2}$$ + $$\frac{16}{7}$$ - $$\frac{7}{2}$$
x = $$\frac{21 + 32 - 49}{14}$$
x = $$\frac{4}{14}$$
x = $$\frac{2}{7}$$
Hence, the number is $$\frac{2}{7}$$
