Answer:

Solution given:

time [t]=3years

principal [p]=Rs2400

rate[r]=?

simple interest [S.I]=Rs 576

we have

S.I=ptr/100

576=2400*3*r/100

576=72r

r=576/72

r=8%

now

principal [p]=Rs 4200

time[t]=2years

rate[r]=8%

simple interest [S.I]=?

we have

S.I= ptr/100=4200*2*8/100=Rs 672

<u>The</u><u> </u><u>required</u><u> </u><u>interest</u><u> </u><u>is</u><u> </u><u>Rs</u><u> </u><u>6</u><u>7</u><u>2</u><u>.</u>

4 7/8 X 2= <br> can someone explain how to work this out?
Ahat [919]
To answer this, first multiply 7/8 by 2. To do that, multiply the numerator, 7, by 2 to get 14, which is 14/8. This is an improper fraction, and simplified it is 1 6/8. That is also equal to 1 3/4. Then multiply 4 by 2 to get 8 and add that to 1 3/4 to get your final answer: 9 3/4. Hope this helps!
