Answer 1

Answer:

27720

Step-by-step explanation:

sum borrowed =PTR/100

P=92400

R=15%

T=2

= 92400 x 2 x 15 /100

= 924x2x15

=31860x2

=27720

therefore sum borrowed is 27720

Answer 2

Answer:

saima is paid into last of term so ,

92400 is money with intrest

in your questions not notified that intrest calculate compound or simple so we calculate simple interest

i = PRN/100 there is,

i = PRN/100 there is,i = x

i = PRN/100 there is,i = xP = 92400-x

i = PRN/100 there is,i = xP = 92400-xR = 15

i = PRN/100 there is,i = xP = 92400-xR = 15N = 2

answer :

x =( 92400-x ) (15) (2) / 100

x = 92400-x(3)/10

10x = 3(92400-x)

10x = 277200 - 3x

13x = 277200

x = 277200/13

x = 21323 is intrest

sum of borrowed = 92400-21323 = 71077 rs
