Remaining money after spent on accommodation = 56% of Ayush salary
Money spent on study material = (1/8) * 56% of Ayush salary = 7% of Ayush salary
Money spent on buying some clothes= (5/7) * (49% of Ayush salary) = 35% of Ayush salary
Savings of ayush = 14% of Ayush salary
We want to know 7% of Ayush monthly salary
Given - Savings of ayush = 14% of Ayush salary = (1/6)*(1/12)* 252000
Money spent on study material = 7% of Ayush monthly salary= 252000/144 = 1750
Money spent on study material = (1/8) * 56% of Ayush salary = 7% of Ayush salary
Money spent on buying some clothes= (5/7) * (49% of Ayush salary) = 35% of Ayush salary
Savings of ayush = 14% of Ayush salary
We want to know 7% of Ayush monthly salary
Given - Savings of ayush = 14% of Ayush salary = (1/6)*(1/12)* 252000
Money spent on study material = 7% of Ayush monthly salary= 252000/144 = 1750

Given:
1. Ayush spent 44% of his monthly salary on accommodation and 1/8tℎ of the remaining salary on study material.
2. He also spent 71 (3/7)% of the remaining salary on buying some clothes and remaining amount he saves.
Asked: If saving of Ayush is 16 (2/3)% of Abhi’s monthly salary then find Ayush’s expense on study material if Abhi’s annual salary is 252000.
Let Ayush's salary be x
Ayush's expenses on accommodation = .44x
Ayush's expenses on study material = .56x * 1/8 = .07x
Ayush's expenses on clothes = 71 (3/7) % * (x - .44x -.07x)
Ayush's savings = 28 (4/7) % * (x - .44x -.07x) = = 16 (2/3)% * 252000/12
(2/7)(.49x) = (5/30)*252000/12 = (5*700)
x = 5*70000*(7/2)/49 = 25000
Ayush's expenses on study material = .07*25000 = 1750
IMO C
