Question:-

• Unil bought a 3-year-old machine from Anil for 7.29.000. Its value decreases by 10 p.c.p.a. What was the price of the machine when Anil bought it?

To Find :-

• Find the price of the machine when Anil bought it.

Solution :-

☆ Formula to be Used :-

${\boxed{ \blue { \bf \bigstar \: A = P(1 ± \dfrac{ R }{ 100 } )}^{\blue{T} } \: \blue{\bigstar} }}$

We have to find the price of the machine :-

Let the price of machine be 'x'

$\longmapsto \rm \: 729000 = x{( 1 - \dfrac { 10 } { 100 } ) }^{ 3 }$

$\longmapsto \rm \: 729000 = x{ ( 0.9 ) }^{ 3 }$

$\longmapsto \rm \: x = \cancel \dfrac{ 729000 }{ 0.729 }$

$\underline { \boxed { \purple { \longmapsto \bf x = Rs \: 10,00,000 \qquad \star }}}$

Hence, the price of the machine is 10,00,000 Rs.
