Xian and his cousin kai both collect stamps. xian has 60 stamps, and kai has 76 stamps. the boys recently joined different stamp-collecting clubs. xian's club will send him 12 new stamps per month. kai's club will send him 8 new stamps per month. after how many months will xian and kai have the same number of stamps? how many stamps will each have?

no. of stemps to Xian = 60
no. of stamps to Kai = 76

After joining the club:-

1st month
Xian = 60+12=72
Kai = 76+8 = 84

2nd month
Xian = 72 +12 = 84
Kai = 84 +8 = 92

3rd month
Xian = 84 + 12 = 96
Kai = 92 + 8 = 100

4th month
Xian = 96 +12 = 108
Kai = 100 + 8 = 108

So after four month they will have the equal stamps which were 108.

HOPE IT HELPS YOU.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
