Q1
Current: M=1/4R
Mark: [___] [++++++++++++24++++++++++++] [___] [++++++++++++24++++++++++++]
Ronaldd: [___] [___] [___] [___] [++++++++++++24++++++++++++] [++++++++14+++++++]
[++++++++++++24+++++++++++ ]
[___] [___] [++++++++14+++++++]
[___] = 5 Mark's age now x 4= 20
Ronaldd's current age is: 20
Q2
Janis: [___[++++ ] ++++++55+++++++++]
Lilin: [________] [________] [________]
2.5 [________] = 55
[________] = 22
Janis bought 22 ice cream sticks.
Q3:
I guess the Q should be when Hakim received $133, Hakim will have 4 time ...... If both received $133, it will never happened the 4 times situation if 13:8 ratio had been preset.
Hakim: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_].[_] [_] [_] [+++++++++++++++++++++++++133 +++++++++++++++++++++++]
Suresh: [_] [_] [_] [_] [_] [_] [_] [_]
[___________________] [____________________] [_____________________] [______________________]
4x8 units = 13 units+133
19 units = 133
1 unit= $7
Hakim had 13 units T first
13 x 7 = $91
Hakim had $91,at first

This is the working for correct answer(question 1):
M current age>5
R current age>20
In 24 years, M is 29 and R is 44
29x2=58
5844=14
This is the working for correct answer(question 2):
J>2u
L>6u
half of J is 1u
6u1u=5u
55/5=11
11x2=22
This is the working for correct answer(question 3):
Before:
H:13
S:8
Process:
+133
End:
H:4
S:1
(13u+133)/4=(8u+133)/1
13u+133=4x(8u+133)
=32u+532
32u13u>532133
19u>399
1u>21
13u>21x13
=273
Hope these workings helped!
