Explanation & Answer

For $70 saving of susan     jane saving is $21

hence 70 :90 :: 21:x

solving 70x = 90*21

x = 90*21/70 =27

hence for $90 saving of Susan , Jane will be saving $27  (Answer)

(2)

if Jane saved $252 then let y is saving of Susan

70 : y::21:252

solving we get,   21y = 252*70

or,   y = 252*70/21 = $ 840.

Answer : Susan Saving $840
