6) Rs 157.2
7) Rs 800
8) Rs 700
9) Rs 900
10) None of these

Solution

SI = PRT/100
=> 78.6 = P *5*2/100
=> P = 78.6*10 = 786

Correct Option: 2 Best Solution (13)

G.S.Kantharao   7 years AGO

Simple Intrest= ₹78.6
Rate of Intrest= 5℅
Time period = 2yrs
Principal = 100I/RT
=(100*78.6)/(5*2)=₹786
Hence the right option is 2.

Let the sum be Rs. x, then
S.I. at 5% in 2 years = x*5*2/100 = 78.6
=> x=Rs. 786

Sum = (100*SI)/(R*T)
= (100*78.6)/(5*2)
= 7860/10
= Rs 786

SUBHAM KUMAR ARYA   7 years AGO

Let the sum be Rs x.
SI=x*r*t/100,
now put SI=78.6, r=5, t=2 & find x.
x= Rs 786

Simple intrest =ptr/100
78.6=p*2*5/100
78.6=p/10
p= 786 rs
p= sum =786 /_

for 2 yrs interest - 10%
sum - 100%(78.6)
= 786

Parveen Soni   7 years AGO

S.I=(amount*rate*time)/100 so ==>
78.6=(?*5*2)/100 ==>
?=786

yogesh tambatkar   7 years AGO

simple Interest formula is
I=sum *Rate * Time in years
on substituting values we get value of sum=786

s.i=p*r*t/100
78.6=p*5*2/100 solve this we get
p=786
