Under new rules of submission of printouts, for every 3 color printouts, Aman can submit only 2 B&W printouts. Calculate the maximum printouts Aman can submit.

General Solution:

Total printouts by all three: 700

Aman's printouts:

Total: 200

70% B&W, so 30% color

B&W: 0.7 × 200 = 140

Color: 0.3 × 200 = 60

Ratio of color printouts by Aman : Bhavna : Chirag = 1 : 2 : 3

Aman's color printouts = 60 (from above)

So, ratio 1 part = 60

Therefore:

Bhavna's color = 2 × 60 = 120

Chirag's color = 3 × 60 = 180

Bhavna's color printouts are 20% more than her B&W printouts:

Let Bhavna's B&W = x

Then, color = x + 0.2x = 1.2x

We know color = 120, so:

1.2x = 120

x = 120 / 1.2 = 100

So, Bhavna's B&W = 100, color = 120

Total for Bhavna: 100 + 120 = 220

Bhavna and Chirag have the same number of B&W printouts:

Bhavna's B&W = 100, so Chirag's B&W = 100

Chirag's color = 180 (from ratio)

Total for Chirag: 100 + 180 = 280

Let's check the total printouts:

Aman: 200
Bhavna: 220

Chirag: 280

Total: 200 + 220 + 280 = 700 (matches given)

Summary of Printouts:

Aman:
B&W: 140
Color: 60
Total: 200

Bhavna:
B&W: 100
Color: 120
Total: 220

Chirag:
B&W: 100
Color: 180
Total: 280

Calculations:

Aman can submit 2 black & white (B&W) printouts for every 3 color printouts.

Aman's Printouts:

B&W: 140

Color: 60

Maximum B&W based on colors:

Aman has 60 color printouts.

He can submit = (2/3) × 60 = 40 B&W printouts based on his color printouts.

Compare to actual B&W: Aman has 140 B&W printouts but he can only submit 40 based on his colors.

Total submissions:

He can submit all 60 color printouts.

He can only submit 40 black and white printouts.

Total Submissions: 60 + 40 = 100

Thus, the maximum printouts Aman can submit is 100.
