Question

a =⅓ , b = ⅕ ആയാൽ a + b/ab എത്ര?

• A. 15/8
• B. ⅛
• C. 8
• D. 8/15

Answer 1

Answer:

C. 8

$a= \frac{1}{3} ;; b= \frac{1}{5}$

$a + \frac{b}{ab}$

$ab=\frac{1}{15}$

$\frac{b}{ab}= \frac{1/5}{1/15}$

$\frac{b}{ab}= \frac{1}{5} \times \frac{15}{1} =3$

$a + \frac{b}{ab} = 3 + \frac{1}{3}$

$=\frac{10}{3}$
