Question

meria and sara together had collected 550 foreign stamps. sara had 40 stamps more than double the number of stamps merin had. find the number of stamps each one collected.

Answer 1

Answer: Number of stamps of Meria are 170 and that of Sara are 380.

Step-by-step explanation:

Let the number of stamps of Meria be x        ... 1

No. of stamps Sara had = 40 + 2x

Total stamps = 550

=> No. of stamps Meria had = 550 - (40+2x)

:.      x = 550 - (40+2x)            (from ...1)

       x = 550 - 40 - 2x

       2x + x = 550 - 40

       3x = 510

       x = 510/3

       x = 170

No. of stamps of Sara = 40+2x = 40+ 2(170) = 40+340 = 380
