SSC CGL Tier II - 18 January 2025 - Shift I • Quantitative Aptitude • Q29

a7×b8×c7a9×b5×c4\frac{a^7\times b^8\times c^7}{a^9\times b^5\times c^4} in simplified form is:

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. (a-2) × (b3) × (c3).

xm/xn = x(m - n)

Now, (a7 × b8 × c7)/(a9 × b5 × c4)

= a(7 - 9) × b(8 - 5) × c(7 - 4)

= (a-2) × (b3) × (c3)

Therefore, the simplified form is (a-2) × (b3) × (c3).
