$\large\underline{\underline{\maltese{\purple{\pmb{\mathscr{\:Given :-}}}}}}$

• ➻ Principle = ₹ 6500
• ➻ Amount = ₹ 8450
• ➻ Rate = 12 %

$\large\underline{\underline{\maltese{\gray{\pmb{\mathscr{\: To \: Find:-}}}}}}$

• ➻ Time = ?

$\large\underline{\underline{\maltese{\orange{\pmb{\mathscr{\: Solution:-}}}}}}$

❒ Formula Used :

Simple Interest :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{S.I = Amount - Principle }}}}}$

Time :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{T = \dfrac{S.I \times 100}{P \times R}}}}}}$

➢Here :

• ➳ T = Time = ?
• ➳ S.I = ?
• ➳ P = Principle = 6500
• ➳ R = Rate = 12 %
• ➳ Amount = 8450

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Finding the Simple Interest :

$\qquad{\dashrightarrow{\sf{S.I = Amount - Principle }}}$

$\qquad{\dashrightarrow{\sf{S.I = 8450 - 6500 }}}$

$\qquad{\pink\longrightarrow{\blue{\underline{\sf{ S.I = ₹ 1950}}}}}$

❒ Now finding the Time :

$\qquad{\dashrightarrow{\sf{T = \dfrac{S.I \times 100}{P \times R} }}}$

$\qquad{\dashrightarrow{\sf{T = \dfrac{1950 \times 100}{6500 \times 12} }}}$

$\qquad{\dashrightarrow{\sf{T =\cancel \dfrac{195000}{78000} }}}$

$\large\qquad{\qquad{\color{maroon}{:\longmapsto{\underline{\boxed{\sf{Time = 2.5 \:years}}}}}}{\pink{\bigstar}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Therefore :

❝ The time is 2.5 years. ❞
