(a)
205-30=175
R 【remaining】
⅝ of R ($ value) ⇒
175×5u÷5 = 175u
R (⁴⁄₇ of T) = 8×175u
³⁄₇ of T【$ total value】
= 30M + ? A
= 3×( 8×175u)÷4
= 1050u
$ total value for A 【apples】
A=1050u-30×5u
= 900u
900u÷3u = 300 (Ans)
(b) difference unchanged
at first
M : A : A-M=205:300: 95
in the end 【left】
M : A : A-M= 1: 6 : 5
95÷5=19
change 【used】
205 - 1×19
= 300-6×19
= 186 (Ans)
