Answer 2

☯GIVEN :

• Amount (A) = Rs 14160

• Rate (R) = 6%

• Principal (P) = 12000

☯TO FIND :

• Time (T) .

☯ FORMULAE REQUIRED :

• $\bigstar{ \underline{\boxed {\purple{ \bf SI = A -P}}}}$

• $\bigstar{\underline {\boxed{ \purple{ \bf{T = \dfrac{SI\times 100}{P \times R} }}}}}$

➲SOLUTION :

Substituting the given values in the First Formula :

$:\implies{ \sf{SI = A -P}}$

$:\implies{ \sf{SI = 14160 - 12000}}$

$:\implies { \underline{ \boxed{ \bf{SI = Rs\: 2160}}}}$

Substituting the given values in the Second formula :

$:\implies{\sf{T = \dfrac{SI\times 100}{P \times R} }}$

$:\implies{\sf{T = \dfrac{\cancel{2160}\times \cancel{100}}{\cancel{12000}\times \cancel{6}} }}$

$:\implies{ \underline{ \boxed{ \blue{\bf{T = 3 \: years}}}}}$

$\huge{\pink{\therefore}}$ Time = 3 years.
