Lets say there were 6m climbers

so number of staff members = 14+m

But its given that

2(14+m) = 6m

28 + 2m = 6m

4m =28

Hence m = 7.

Thus

thanks adarsh

if we let**a**be climbers and**b**staff then

... i know your answer is correct (because the book says (Hi)), but im confused as to why statements like 'twice as many climbers than staff' gives

and not

if a = climbers and b = staff and there are "twice as many staff as climbers" (keywords of the problem), then if we multiply the number of climbers by 2, then that's how many staff we have. Right? Hence, 2 times the number of climbers = the number of staff. Or better yet a=2b.

Consider these things

a is twice of b

.

.

Take an example

6 is twice of 3

6 = 2 * 3

similarly

a = 2 * b

--this might help

try to think taking examples (Smile)
