Mr.Arun borrowed 22,000 from a bank at 8% per annum,

bank if he repays the loan in (1) 2 years (ii) 3 years 9 month

Answer 1

${\huge{\mathfrak{\red{solution}}}}$

${\sf{principle \: = 22000rs}} \\ {\sf{rate \: = 8\%}}$

${\large{\mathtt{\blue{formula \: used \: }}}}\\ {\large{\boxed{\mathtt{\blue{\frac{p \times r \times t}{100}}}}}}$

${(1) \: time = 2 \: years} \\ simple \: interest \: = \frac{p \times r \times t}{100} \\ { \implies{\frac{\cancel{22000} \times 8 \times 2}{ \: \cancel{100}}} } \\ {\implies{220 \times 8 \times 2 }}\\{ \implies{\boxed{3520rs}}}$

${(2) \: time = 3 \: years \times \frac{9}{12} = 3 \times \frac{3}{4} } \\ simple \: interest \: = \frac{p \times r \times t}{100} \\ { \implies{\frac{\cancel{22000} \times {\cancel{8}} \times 3 \times 3}{ \: \cancel{100} \times {\cancel{ 4}}}} } \\ {\implies {220 \times 2 \times 3 \times 3 }}\\{ \implies{\boxed{3960rs}}}</p><p>$
