Answer 1

$\huge\mathfrak{Answer:-}$

Let my age be $x$ years.

My Grandson's age be $x$months.

$= \frac{x}{12} \:years$

$= ( \frac{x}{12} ) \times 365 \: days$

My Daughter's age

$= ( \frac{x}{12} ) \times 365 \: weeks$

$= ( \frac{x}{12} ) \times 365.7 \: days$

$= \frac{ \frac{x}{12} \times 365.7 }{365}$

$= \frac{7x}{12} \: years$

Now,

My age + Grandson + Daughter = 120

$x + ( \frac{x}{12} ) + ( \frac{7x}{12} ) = 120$

$12x + x + 7x = 1440$

$20x = 1440$

$x = \frac{1440}{20}$

$x = 72$

Therefore,

Correct option B) 72

Answer 2

Hi!!

Here's ur answer..

Given..

Let my age be x years

My Grandson's age be x months

= × / 12 × 365 days

My daughter's age .

= × ÷ 12 ×365.7 days

×/12 × 365.7/ 365

= 7×/12 years

× + (×/12) + 7(×/12) =120

12× + × + 7× = 1440

20× = 1440

× = 1440/20

= 72

Therefore the correct answer is 72 (Option B)

Hope it's helpful to you..
