Question : Which one of the following has greatest mass?
Option 1: electron
Option 2: proton
Option 3: neutron
Option 4: hydrogen nucleus
Correct Answer: neutron
Solution : The correct option is neutron.
The neutron has the greatest mass among the proton, neutron, electron, and nucleus of hydrogen. The mass of a proton is 1.672621777(74) × 10-27 kg. The mass of a neutron is 1.674927498(94) × 10-27 kg. The mass of an electron is 9.1093837015(28) × 10-31 kg. The mass of a hydrogen nucleus is 1.674927498(94) × 10-27 kg. A neutron's mass is somewhat larger than that of a proton. An electron's mass is substantially lower than that of a proton or neutron. Because a hydrogen nucleus contains just one proton, its mass is the same as that of a proton.

Question : A shopkeeper offers two successive discounts of 15% and 20% on an article and is still able to earn a 70% profit. If he offers a single discount of 30%, what will his profit percentage be?
Option 1: 70%
Option 2: 75%
Option 3: 65%
Option 4: 50%
Correct Answer: 75%
Solution : Given,
Successive discounts = 15% and 20%
Profit = 70%
We know,
Selling Price = $\frac{100+\text{Profit%}}{100}\times$ CP, where CP is the cost price.
Let the cost price of an article be Rs. 100
⇒ Price after first discount of 15% = 100 – 15% of 100 = Rs. 85
⇒ Price after second discount of 20% = 85 – 20% of 85 = 85 − 17 = Rs. 68
So, the original cost Price = $\frac{100}{100+70}$ × 68 = $\frac{10}{17}$ × 68 = Rs. 40
To sell the article at a 30% discount,
Selling Price = 100 − $\frac{30}{100}$ × 100 = Rs. 70
⇒ Profit = SP – CP = 70 – 40 = Rs. 30
⇒ Profit Percentage = $\frac{\text{Profit}}{\text{CP}}$ × 100 = $\frac{30}{40}$ × 100 = 75%
Hence, the correct answer is 75%.
Question : If $a= 9.6,b= 4.44,$ and $c= 5.16$, then the value of $a^3- b^3- c^3- 3 abc$ is:
Option 1: 0
Option 2: –1
Option 3: 2
Option 4: 1
Correct Answer: 0
Solution : Given: $a= 9.6,b= 4.44,$ and $c= 5.16$
We know,
If $a-b-c=0,$ then $a^3-b^3-c^3-3abc=0$
Here, $a-b-c=9.6-4.44-5.16=0$
So, $a^3-b^3-c^3-3abc=0$
Hence, the correct answer is 0.
