You can put this solution on YOUR website!
Let +x+ = amount he had at first
He had +x+-+682+ after buying pendant
Then he spent 1/10 of that, so he had 9/10
left, so, he has left
+%28+9%2F10+%29%2A%28+x+-+682+%29+
and you are told he has:
+%28+9%2F10+%29%2A%28+x+-+682+%29+=+%28+3%2F7%29%2Ax+
Multiply both sides by +70+
+63%2A%28+x+-+682+%29+=+30x+
+63x+-+63%2A682+=+30x+
+33x+=+63%2A682+
+x+=+%2821%2F11+%29%2A682+
+x+=+21%2A62+
