    Solution
    $$\Rightarrow$$  Here $$I=Rs.1000,\,R=2\%,\,T=4\,years$$

    $$\Rightarrow$$  $$P=\dfrac{I\times 100}{R\times T}$$

    $$\Rightarrow$$  $$P=\dfrac{1000\times 100}{2\times 4}$$

    $$\Rightarrow$$   $$P=Rs.12,500$$
  • Question 3
    1 / -0
    Convert $$\dfrac{14}{40}$$ into percentage.

  • Question 4
    1 / -0
    Ramila buys a scooty at Rs 38,000. After 2 years she sold it at Rs 30,400. Then, how much percentage profit or loss Ramila gets?
    Solution
    Given
    Ramila buys a scooty at Rs.38,000.
    So Cost Price = 38000;
    After 2 years she sold it at Rs.30,400.
    So Selling Price = 30400
    Here Cost Price is greater than Selling Price..so Loss exists.....
    We know that...
    Loss. = Cost Price - Selling Price
    Loss = 38000- 30400
    Loss= 7600
    loss Percentage =( loss /Cost Price )×100
    =( 7600/38000)×100
    =20%
    So  loss Percentage= 20%

    $$\displaystyle \frac{14}{3}=\frac{14\times 3}{3\times 3}$$$$\displaystyle =\frac{42}{9}$$

    $$\Rightarrow \dfrac{28}{6}, \dfrac{42}{9}$$ are Equivalent ratios of $$\displaystyle \frac{14}{3}$$
