Given :- Rimi scored 28 out of 35 in a test and Mimi scored 40 out of 50 in another test.
To Find :- Whose performance is better ?
Solution :-
Rimi :-
→ Total marks = 35
→ Rimi scored marks = 28
So,
→ % of marks scored by rimi = (scored marks × 100) / Total marks = (28 × 100) / 35 = 80% --------- Equation (1)
Mimi :-
→ Total marks = 50
→ Mimi scored marks = 40
So,
→ % of marks scored by mimi = (scored marks × 100) / Total marks = (40 × 100) / 50 = 80% --------- Equation (2)
from Equation (1) and Equation (2) we get,
→ 80% = 80%
therefore,
→ % of marks scored by rimi = % of marks scored by mimi .
Hence, Both Rimi and Mimi have same performance .
