Correct Answer: 25

Solution : Prime factorization of $69120 = 2^9 × 3^3 × 5$
For the number to be a perfect cube, all the exponents must be multiples of 3, thus the above number must be multiplied by $5^2=25$
Hence, the correct answer is 25.

Correct Answer: 25,000 kg

Solution : Given: 15% of orange = 15000 kg
⇒ 1% = 1000 kg
percentage distribution of musk melon and watermelon together = (20 + 5) = 25%
So, 25% = 25 × 1000 = 25000 kg
Hence, the correct answer is 25000 kg.

Correct Answer: 585

Solution : Sum of an arithmetic series = $\frac{n}{2} × (\text{first term + last term})$
⇒ Two digit numbers divisible by 9: 18, 27, 36,..., 99 (Total terms = 10)
So, the sum = $\frac{10}{2} × (18 + 99) = 585$
Therefore, the sum of all two-digit

Correct Answer: $\frac{3}{5}$

Solution :

$\tan \theta=\frac{8}{15}=\frac{\text{Perpendicular}}{\text{Base}}$
$\therefore$ Hypotenuse = $\sqrt{8^2+15^2}=\sqrt{289}= 17$
So, $\sin \theta=\frac{8}{17}$
$\sqrt{\frac{1-\sin \theta}{1+\sin \theta}}=\sqrt{\frac{1-\frac{8}{17}}{1+\frac{8}{17}}}=\sqrt{\frac{\frac{9}{17}}{\frac{25}{17}}}=\sqrt{\frac{9}{25}}=\frac{3}{5}$
Hence, the correct answer is $\frac{3}{5}$.

Correct Answer: Son's daughter
