How to do both qns?
Tks

(a)

If Ken was left with u sweets in the end, he had 4u chocolates in the end given the ratio 1:4.

Since Ken gave u sweets to James, James was left with (u – 17) sweets in the end and he had 9(u – 17) chocolates in the end given the ratio 1:9.

Since Ken had eaten 37 chocolates,

4u + 37 = 9(u – 17)

4u + 37 = 9u – 153

5u = 190

u =38

So Ken gave 38 sweets to James.

(b) Ken received (4u + 37) chocolates from James,

4u + 37 = 4*38 + 37 = 189

189 * 2 = 378

James bought 378 chocolates.

Thanks for the solution.

(a) If James bought 4u chocolates, he gave 2u chocolates and left with 2u. Ken ate 37 chocolates and left with (2u – 37 ) chocolates in the end.

As Ken in the end had sweet : chocolate = 1 : 4

Ken had (2u – 37) /4 sweet in the end.

And James had ( (2u – 37 ) / 4 ) – 17 sweets in the end and given the ratio sweet : chocolate = 1 : 9

9( ((2u -37)/4) – 17 ) = 2u

9((2u – 37) /4 ) – 153 = 2u

18u – 333 – 612 = 8u

10u = 945

u = 94.5

(189 – 37)/4 = 152/4 = 38

James gave 38 sweets to Ken.

(b) 4u = 378

James bought 378 chocolate .

Check: 378/2 = 189

189 – 37 = 152

38 : 152 = 1 : 4

38 – 17 = 21

21 : 189 = 1 : 9 Checked

Lol… I read this question until I go bonkers.  It’s gotta be one of those questions that turn humans into pretzels.  I have to slowly read your solution to grasp it.  Thank you!
