SSC CHSL 2024 PYQ — Question 69

The correct answer is Option 4 i.e. A and D are equal.

⇒ A = $\frac{9}{16}\div\frac{25}{36}$ 

⇒ A = $\frac{9}{16}\times\frac{36}{25}$ = $\frac{81}{100}$

Now,

⇒ B = $9\div[(16\div25)\div36]$ 

⇒ B = $9\div{16\over900}$ 

⇒ B = ${2025\over4}$

Now,

⇒ C = $[9\div(16\div25)]\div36$

⇒ C = ${225\over16}\div36$

⇒ C = ${25\over64}$

Now,

⇒ D = $(9\div16)\div(25\div36)$

⇒ D = ${9\over16}\div{25\over36}$

⇒ D = ${81}\over{100}$

Thus, A and D are equal
