SSC CHSL 2021 PYQ — Question 67

The correct answer is option 4 i.e.  8$\frac{1}{10}$

Evaluate using the BODMAS rule which says, 'Brackets, Order, Division, Multiplication, Addition, Subtraction'

$\frac{{\left[ {\frac{1}{9} \div \frac{1}{9}of\frac{1}{9}} \right] \times \frac{1}{9}}}{{\frac{1}{9} + \frac{1}{9}of\frac{1}{9}}}?$

=$\frac{{\left[ {\frac{1}{9} \times \frac{9}{1}\times\frac{1}{9}} \right] \times \frac{1}{9}}}{{\frac{1}{9} + \frac{1}{9}\times\frac{1}{9}}}$

=$\frac{{{\frac{1}{9} } \ \times \frac{1}{9}}}{{\frac{1}{9} + \frac{1}{9}\times\frac{1}{9}}}$

= 8$\frac{1}{10}$
