Question
In a test, Riya got 40% of the total marks and was short
by 16 marks to pass. Meena obtained 50% marks and secured 4 marks more than the passing marks. What were the passing marks of the test?Solution
ATQ,
Let the total marks of the test be 100x
Marks scored by Riya = 0.40 Γ 100x = 40x
Passing marks = 40x + 16
Marks scored by Meena = 0.50 Γ 100x = 50x
Passing marks = 50x - 4
So,
40x + 16 = 50x - 4
β 10x = 20
β x = 2
Therefore, passing marks = 40x + 16 = 40 Γ 2 + 16 = 96
What will come in the place of question mark (?) in the given expression?
? = (266 Γ 276) Γ· (114 Γ 161) Γ 17
Find the value: (2.4 Γ· 0.06) Γ (3/5) β 7.5
2/5 of 3/4 of 7/9 of 7200 = ?
What will come in the place of question mark (?) in the given expression?
4 Γ ? ...
- What will come in place of the question mark (?) in the following questions?
x= β(4 Γ β(16 Γ β(4 Γ β(16 Γβ¦β¦ β)) ) )Β
(168 Γ· 12 + 19 Γ 64)/(22+1) = ?
150% of 84 + ?% of 130 = 230
48 Γ· 6 Γ β25 + 13 Γ 8 = ?
2/5 of 3/4 of 7/9 of 7200 = ?
