Question

5 वर्ष पूर्व गीता की आयु कमला की आयु की 3 गुना थी। 10 वर्ष बाद गीता की आयु कमला की
आयु की 2 गुना होगी। दोनों की वर्तमान आयु ज्ञात कीजिए।​

Answer 1

Answer

present age of Kamla = 5 years

present age of Geeta = 10 years

Explanation

Let the present age of Kamla be x years

5 years ago,

Age of kamla = (x- 5)years

Age of Geeta = 3(x-5)years = 3x-15 years

After 10 years,

kamal's age = (x-5)+10 years

Geeta's age = 2(3x-15)+10 years

According to the question,

(x-5)+10 = 2(3x-15)+10

x+5 = 6x-30+10

x+5 = 6x-20

x-6x = -20-5

-5x = -25

minus se minus cancel,

5x = 25

x = 25÷5

x = 5

therefore,

present age of kamla = 5 years

present age of Geeta = (x+5) years = (5+5) years = 10 years
