let first parrt is x and second part is y then x+y=50000----------eq1
total profit=profit on x +profit on y
7000=(x*10*1)/100 + (y*20*1)/100
70000=x+2y-----------------------------------eq2
70000=50000+y
so y=20000 then x =50000-20000=30000
first part =30000

30,000
sol. let x was given to a with 10% interest.
then b got 50,000 - x
interest = p*t*r /100
so
7000 =((50000 - x)*1*20)/100 +(x*1*10)/100
700000 = 1000000 - 10x
x = 30000

let the total principle be P=50000
its divided as
p1=x
p2=50000-x
SI1= (p1*n*r)/100 =(x*10*1)/100 =x/10
SI2= (p2*n*r)/100 =((50000-x)*20*1)/100 =(100000-2x)/10
now given,
SI1+SI2=7000
x/10 + (100000-2x)/10
therefore,
x=30000

30000
20% of 20000 = 4000
10% of 30000 = 3000

4000+3000=7000

Madhuri lad  (11 years ago)

Divide 50000 in 2 part x and (50000-x)
10% of x=x*(10/100) and 20% of (50000-x)= (50000-x) *(20/100)
[x*(10/100)]+[(50000-x) *(20/100)]=7000
so x=30000

LET 50,000 DIVIDE INTO TWO PARTS THAT IS X AND Y,
NOW, 10% OF X AND 20% OF Y=7000=((10*X)/100)+((20*Y)/100)---1
AND X+Y=50,000---2
AFTER SOLVING THIS 2 EQUATIONS 1 AND 2 WE GET X=30,000 Y=20,000
NOW AT THE END OF 1 YEAR
MONEY RETURN BY 10% WILL BE =30000+((30,000*10)/100) THAT IS=33,000
SO ANSWER IS 33,000
