Answer:

the answer of this math is। 150

Answer 2

Step-by-step explanation:

Given :-

• Principal = ₹1500
• Rate = 8% per annum
• Time = 15 months

To Find :-

• Simple Interest

Solution :-

~As we can see the time is given in months. So, firstly we need to convert it into years.

» In order to convert, follow these steps :

• In 1 year there are 12 months.
• So, to get 15 months into years, we will divide it by 12.

$\leadsto \sf \dfrac{15}{12} \\ \\ \leadsto \sf \cancel\dfrac{15}{12} \\ \\ \leadsto \boxed{\bf \dfrac{5}{4}}$

★ Now, we know that,

$\bf \longrightarrow \: \underline{\boxed{ \bf Simple \: Interest = \frac{ P \times R \times T }{100} }}$

Substituting the values in the formula,

$\sf \longrightarrow \: Simple \: Interest = \dfrac{ 1500 \times 8 \times 5 }{100 \times 4} \\ \\ \sf \longrightarrow \: Simple \: Interest = \dfrac{ 15 \cancel{00} \times 8 \times 5 }{1 \cancel{00} \times 4} \\ \\ \sf \longrightarrow \: Simple \: Interest = \dfrac{ 15\times \cancel8 \times 5 }{ \cancel4} \\ \\ \sf \longrightarrow \: Simple \: Interest = 15 \times 2 \times 5 \\ \\ \sf\longrightarrow \: Simple \: Interest = 15 \times 10 \\ \\ \longrightarrow \boxed{\bf\: Simple \: Interest =Rs. \: 150} \: \bigstar$

Hence, Simple Interest is ₹150.
