Question

(iii) Find the ratio of the number of boys to the number of girls. A certain sum of money is divided in the ratio 2. 3. If the second part is 3750, find the total amount.​

Answer 1

$6250$

Step-by-step explanation:

$Let, \: \:first \: \: part = 2x \: \: \: and \: \: \: second \: \: part=3x \\ A/Q, \: \: \: second \: \: part = 3750 \\ = > \: \: 3x = 3750 \\ = > \: \: x = 1250 \\ Now, \: \: \: total \: \: amount = 2x + 3x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5 \times 1250 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6250$

Answer 2

Answer:

here; A certain sum of money is divided in the ratio 2: 3.

●let the certain money be x.

# so, 2+3=5

♢ x/5= 1st part

A/Q

3rd part: x/5 × 3 = 3750.

therefore, x = 3750 × 5/3 = 6250

Hence total amount will be :-

2x +3x = 5x

5x = 5 × 6250 = 31250
