Answers
Answer:the present age of woman is 33 yearsAnd daughter's age is 10 years.Step-by-step explanation:Let the present age of a woman is xAnd the present age of her daughter is y.the present age of a woman is 3 years more than 3 times the age of a Daughter 3 years that means:x=3+3yx=3+3y\Rightarrow x-3y=3⇒x−3y=3 (1)And also, 3 years hence the women's age will be 10 years more than twice the age of her daughter that means:x+3=10+2(y+3)x+3=10+2(y+3)\Rightarrow x+3=10+2y+6⇒x+3=10+2y+6\Rightarrow x-2y=13⇒x−2y=13 (2)On solving (1) and (2) by subtracting (2) from (1)Sign of (2) changes we get:-x+2y=-13−x+2y=−13 (4)Now, solving(1) and (4) we get:-y=-10−y=−10y=10y=10Substitute y=10 in (1) we get:x-3(10)=3x−3(10)=3x=33x=33So, the present age of woman is 33 yearsAnd daughter's age is 10 years.
