Question

The ages of Amit and Sumit are in the ratio 2:3. After 15 year, the ratio of their ages will be 3:4. find their present ages

Answer 1

hey mate

here's your answer ,

the age of amit = 2x years

the age of sumit = 3x years

after 15 years,

age of amit = 2x + 15 years

age of sumit = 3x + 15 years

according to the question,

》 $\huge\frac{2x + 15}{3x + 15}$ = $\huge\frac{3}{4}$

》 4(2x+15)=3(3x+15)

》8x + 60 = 9x + 45

》 8x - 9x =45 - 60

》 -x = -15

》 x = 15

the age of amit = 30 years

the age of sumit = 45 years

hope it helps you mate!!!

be brainly

keep asking

thanks for asking this question

Answer 2

=> CONSIDER the common constant as X

=> Amit = 2X

=> SUMIT = 3X

=> AFTER 15 YEARS

=> AMIT = 3 X

=>SUMIT = 4X

=> SO, the equation:

=> (2 X + 15) + 3 X + 15 = 3x + 4x

=> 5x + 30 = 7x

=> 30 = 7x - 5x

=> 2x = 30

=> x = 30 ÷ 2

=> x = 15


$\textbf{PRESENT\:AGES}$


=> AMIT = 2 X


=> 2 × 15


=> 30


=> SUMIT = 3 X


=> 3 × 15


=> 45

THEREFORE THE PRESENT AGES ARE:

AMIT = 30 YEARS

SUMIT = 45 YEARS
