Solution:

1). Let the number be x,
Then, 45% of x – 25% of x = 16
à x/100 (45-25) = 16
à x/100 ×20=16
à x = 80
Hence, 7.5% of 80 = 7.5/100 × 80 = 6
Answer: d)

2). Let the number be x.
Then, 12/100 × 75/100 × x – 5/100 × x = 75
     à 9x/100 – 5x/100 = 75 è  4x/100 = 75
à x = (75×100)/4 = 1875
Answer: a)

3). Let the number be x.
Then , 50% of x + 50 = x
à x- (50/100) × x =50
à x/2 = 50 è x= 100
Answer: d)

4). Let the number be x
Then, x-14 = 90% of x
à x-90% of x = 14
à x – (90/100) × x = 14
à 10x/100 = 14
à x=14/10 × 100 = 140
Answer: c)

5). Let the number be x.
Then, x – 25% of x = 10.8
x-(25/100) ×  x = 10.8
75x/100 = 10.8
x = (10.8 × 100)/75 = 14.4
Answer: e)

6). Number of boys = 60% of 5600
= (60/100) × 5600 = 3360
Hence, number of girls = 5600 – 3360 = 2240
Answer: a)

7). Savings of the man = (100 - 85) = 15%
Let the monthly income be Rs.x
Then, 15% of x = 4560
 à (15/100) × x = 4560
à X = (4560×100)/15 = 30400
à Hence, Monthly income of man = Rs.30400
Answer: c)

8). Number of sweets each student gets =20% of 60 = 20/100 × 60 = 12
Number of sweets each teacher gets = 25% of 60 = 25/100 × 60 = 15
Hence, total number of sweets = (12×60 + 15×6) = 720 +90 = 810
Answer: c)

9). Let the investment by Raghu be Rs.x
Then, Mohit = x × 90/100 = Rs. 9x/10
Pradeep = 9x/10 × 120/100 = Rs.108x/100
According to the questions,
x + 9x/10 + 108x/100 = Rs. 17880
à (100x + 90x + 108x) / 100 = 17880
à 298x/100 = 17880 => x=Rs.6000
Answer: a)

10). Passing marks = 175 + 35 = 210
à Maximum marks ×35% = 210
Maximum marks = (210×100)/35 = Rs.600
