Question

The present age of Sita’s father is three times the present age of
Sita. After six years sum of their ages will be 68 years. Find their
present ages.
b) The denominator of a fraction is greater than the numerator by 8. If
the numerator is increased by 17 and denominator is decreased by
1, the number obtained is 3/2. Find the fraction.

Answer 1

Answer:

Only plants are capable of combining simple inorganic substances into complex organic ones capable of sustaining life. An organism which can carry out this method of nutrition is said to be autotrophic which means self-feeding.

Answer 2

Answer:

1)We can verify the answer by using the information given in the question.. Sita's age 6 years later will be 14.25+6=20.25 years. Sita's father's age 6 years later will be 42.75+6=48.75 years.

2)Let the numerator of the rational number be x.So as per the given condition, the denominator will be x + 8.The rational number will be \(\frac{x}{x+8}\)According to the given condition,\(\frac{x+17}{x+8-1} = \frac{3}{2}\) \(\frac{x+17}{x+7} = \frac{3}{2}\) 3(x + 7) = 2(x + 17)3x + 21 = 2x + 343x – 2x + 21 – 34 = 0x – 13 = 0x = 13The rational number will be= \(\frac{x}{x+8}\)= \(\frac{13}{13+8}\)Rational number = 13/21
