Question!

The ratio of present ages of albert and salim is 8:7 4years ago ratio of there ages will be 6:5 find the present ages?

kindly see the answer in the web.!​

Answer 1

Answer:

$8x - 4 \div 7x - 4 = 6 \div 5 \\ 5(8x - 4) = 6(7x - 4) \\ 40x - 20 = 42x - 24 \\ - 20 + 24 = 42x - 40x \\ 6 = 2x \\ 6 \div 2 = x \\ 2 = x$

Albert's age= 16.

Salim’s age = 14.

Answer 2

Given :

• Ratio of present ages of albert and salim is 8 : 7.
• 4 years ago ratio of there ages were 6 : 5.

To Find :

• Find their present ages ?

Solution :

• Let present age of Albert be = 8x
• And present age of Salim be = 7x

Now,

According to the question :

• 4 years ago ratio of there ages were 6 : 5.

➣ Albert's age = 8x - 4

➣ Salim's age = 7x -4

➣ 8x - 4/ 7x - 4 = 6/5

➣ 5( 8x - 4 ) = 6( 7x - 4 )

➣ 40x - 20 = 42x - 24

➣ 2x = 4

➣ x = 2

Now,

• Present age of Albert = 8x = 8(2) = 16 years.
• Present age of Salim = 7x = 7(2) = 14 years.

Hence,

• Present ages of Albert and Salim are 16 and 14 years.
