Answers
little summary-
a) PAINTING b)RAFTING
= adults :children = 1:9 1:3
solution -
(Painting; a) adults : children = 1 : 9
= adults= 5
= children = ( let it be x )
= 1 / 9 = 5 / x
= 1 * x = 9 * 5
= 1 * x = 45
= x = 45 / 1
= x = 45
= no. of children= x = 45
answer (a) = 45
(rafting; b) = aduts : children = 1:3
= no. of chidren = 24
= no. of adults = ? (let it be x )
--(1:3 means 1/3)
= 1/3 = x/ 24
= 1 * 24 = 3* x
= 3*x = 24
= x = 24 / 3
= x = 8
= no. of adults (x) = 8
= answer is 8
