Question

a person take loan of rupee 45000 from 2 banks 1 bank gives 8% rate of interest and 2 bank gives 12% intrest so and the total intrest is 4440 ,so how much rupees loan did he take from 8% rate of interest​

Answer 1

Answer:

loan he take from 8% rate of interest is x = 24000

Step-by-step explanation:

let the loan from taken from bank 1st is x

and loan from bank 2 is let y

x + y = 45000 given

rate of interest by bank 1 = 8%

rate of interest by bank 2 = 12 %

x×8/100 + y×12/100 = 4440

8x + 12y = 444000

2x + 3y = 111000 equation 2

now we have 2 equation

x+ y = 45000

2x+2y = 90000 equation 1

subtract eq 1 from eq 2

(2x + 3y ) - (2x+2y)= 111000 - 90000

y = 21000

then x is

x + y =45000

x +21000 =45000

x = 24000

loan he take from 8% rate of interest is x = 24000
