Data Sufficiency (DS) | Re: If a machine depreciates each year at the rate of 50% of its previou

This is a successive change problem
let x be the value of the machine before depreciating
after depreciating for three years is basically successively losing 50% of its value for three years:

Ques asks\(x*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}<12,000?\)
=> x<96,000 (simplified)

st 1: x is more than 95,000NS
st 2:x*1/2*1/2>24000
x>96000
sufficient
