Jack brought 837 big and small antique vases.
He broke 1/10 of the number of big vases and his friend gave him another 47 small
Hence, the number of small vases that he had was 1/3 of the number of big vases
How many more big vases than small vases had he in the beginning?
Let the number of big vases ==B
Let the number of small vases ==S
B + S ==837....................(1)
0.9B ==Big vases left after 1/10 got broken.
S + 47 - total of small vases.
[S + 47] ==1/3 * 0.9B.......(2), solve for B, S
B==680 - Big vases that he started with.
S==157 - Small vases that he started with.
680 - 157 ==523 difference between Big and Small vases
