Question

alice is is two third as old as her brother. Twelve years before she was half as old as her brother. Find her present age​

Answer 1

Step-by-step explanation:

The area of a trapezium with equal non-parallel sides is 162 m2. If the lengths of the parallel sides are 36 m and 20 m, then find the length of the non-parallel sides.

Answer 2

Answer:

Let us assume 'alice brother's age as X. As alice is twice as old as her brother her age would be 2X.

In 6 years from now there ages would be

Anita's age = 2X + 6, Alice brother's age =X +6

So, according to the question, the sum of there ages after 6 years is 39.

Now the equation would be (2X+6) + (X+6) = 39

After solving the above equation we get, X=9

Now 2X=18 and X=9

So, Now the age of Alicec is 18 .i.e. 2X and her brother's age is 9 .i.e. X.
