Question

Meri and Sarin together had collected 550 foreign stamps. Satin had 40 stamps more than double the number of stamps Meri had. Find the number of stamps each one Collected. ​

Answer 1

Answer:

Meri=x

Sarin=x+40×2=2x+40

x+2x+40=550

3x+40=550

3x=550-40

3x=510

X=170

X+40×2=380

380+170

=550

Hence proved

Answer 2

Answer:

let the number of stamp meri had be X

then the number of stamp sarin had is

40+2X

then

X+40+2X=550

3X=550-40

X=510/3

X=170

then

meri had170 stamps

and satin had 40+2×170

40+340

380stamps
