Let's break it down:
1. Take the 1st pill: Time = 0
2. Take the 2nd pill: Time = 0.5 hours
3. Take the 3rd pill: Time = 1 hour
After taking the 3rd pill, all pills have been taken.
Speed = Distance / Time = 600 m / 30 s = 20 m/s
Convert to km/h: 20 × 3.6 = 72 km/h
Cost Price (CP) from 10% loss:
144 = 90% of CP ⟹ CP = 144 / 0.90 = Rs. 160
For 15% profit:
Selling Price = 160 × 1.15 = Rs. 184
Solve:
6x + 11 = 41 ⟹ 6x = 30 ⟹ x = 5
Now, 2x + 3 = 2(5) + 3 = 13
The formula is: LCM × HCF = Product of the two numbers.
So, 100 × 50 = 50 × x ⟹ x = 100.
Time per item = 1/3 minute, so items per minute = 3
In 10 minutes: 10 × 3 = 30 items
Happiness means خوشی

"All but 2 died" means only 2 are still alive.
