Answer:
It is simple question.
case 1
p =7000
t =2
rate=x
take "R" as "x"
intrest=p*r*t/100
so intrest =140x
case 2
p=2500
r=x
take "R" as "x"
t=4years
intrest=p*r*t/100
intrest=100x
140x + 100x=2400
after solving you will get "x" =10
So,mohit intrest =140x
=140*10
=₹1400
So,mohit intrest =100x
=100*10
=1000
