Question : The difference between the cubes of two given natural numbers is 6272, while the positive difference between the two given numbers is 8. What is the sum of the cubes of the two given numbers?
Option 1: 9728
Option 2: 9684
Option 3: 8000
Option 4: 9600
Correct Answer: 9728
Solution : Given: $a^{3}–b^{3}=6272$ and $a–b=8$ We know that $(a–b)^{3}=a^{3}–b^{3}–3ab(a–b)$ Putting the given value, we have, ⇒ $(8)^{3}=6272–3ab(8)$ ⇒ $24ab=6272–512$ ⇒ $ab=\frac{5760}{24}=240$ ------------------------------------(1) Putting the value of $a=b+8$ we have, ⇒ $(b+8)b=240$ ⇒ $b^{2}+8b–240=0$ ⇒ $b^{2}+20b–12b–240=0$ ⇒ $b(b+20)–12(b+20)=0$ ⇒ $(b+20)(b–12)=0$ ⇒ $b=12,–20$ The value of a natural
Question : If the diameter of a solid hemisphere is 12.6 cm, then its volume is (take $\pi=\frac{22}{7}$):
Option 1: 1,259 cm3
Option 2: 987 cm3
Option 3: 523.908 cm3
Option 4: 1,235.621 cm3
Correct Answer: 523.908 cm3
Solution : Given: Diameter = 12.6 cm ⇒ radius, $r$ = 6.3 cm Volume of the hemisphere = $\frac{2}{3}\pi r^3$ $=\frac{2}{3}\times \frac{22}{7}\times (6.3)^3$ $= \frac{11002.068}{21}=$ 523.908 cm3 Hence, the correct answer is 523.908 cm3.

Question : A hemispherical bowl has a radius of 7 cm. It is to be painted from inside as well as outside. Find the cost of painting it at the rate of Rs. 40 per 20 cm2. (Take the thickness of the bowl as negligible).
Option 1: Rs. 1,232
Option 2: Rs. 1,125
Option 3: Rs. 1,432
Option 4: Rs. 1,550
