Percentage Online Test 1

Number of boys in the college = 60 % of 1335
= 60/100 × 1335
= 80100/100
= 801
Number of girls in the college = Total number of students in the college – Number of boys
= 1335 – 801
=534

Required percentage = 1313/ 1400 × 100
=131300/1400
=93.7

Let the maximum marks be s
Then 72 % of s = 864
72/100 × s = 864
s = (846 × 100)/72
s = 86400/92
s = 1200
Therefore, maximum marks in the examinations are 1200.

Percentage of matches lost = 75 %
Therefore Percentage of matches won (100 – 75) % = 25 %
Let the number of matches played be x.
Then 25 % of x = 45
25/100 × x =45
x = (45 × 100)/25
x = (4500)/25
x = 180
Therefore, the total number of matches played is 180.

Let the quantity of alloy required = x g
Then 36 % of x =340 g
⇒ 36/100 × x = 340 g
x = (340 × 100)/36 g
x = 34000/36 g
x = 944.4 g

Percentage of plot allowed for construction = (13500/18000 × 100) = 75 %.
Thus, the percentage of plot to be left without construction = 100 % – 75 % = 25 %.

Let the total number of eggs in the basket be x
20 % of the eggs are rotten, and eggs in good condition are 68
Therefore, according to the question,
80% of x = 68
80/100 × x = 68
x = (68 × 100)/80
x = 6800 / 80
x = 85
Therefore, total number of eggs in the basket is 85.

Percentage of marks scored by Ayesha = (994/1200 × 100)
= (99400/1200)
= (994/12)
= 83 %
Percentage of marks scored by Sohail = (1020/1500 × 100)
= (102000/1500)
= (1020/15)
= 68 %
Hence, the percentage marks scored by Ayesha is better.

Let sister’s weight be 100 kg.
Then brother’s weight = (100 + 25) kg = 125 kg
If brother’s weight is 125 kg, then sister’s weight is 100 kg.
If brother’s weight is 1 kg, then sister’s weight is 100/125 kg
If brother’s weight is 100 kg, then sister’s weight = (100/125 × 100) kg
Therefore, sister’s weight is 20 % less than that of brother
