Question

Sangi spent his winter holiday in Colorado. The ratio of the number of times he went snowboarding to the number of times he went skiing to the number of times he went snowshoeing was 3 : 1: 2. If he went snowboarding 21 times, how many times did he enjoy the winter activities altogether?

Answer 1

I think it is 42 times
21*1=3*X
X=7
21*2=3*Y
Y=14
14+7+21=42
