Given:

\Delta MNO\cong \Delta PQR

To find:

The length of QR.

Solution:

We have,

\Delta MNO\cong \Delta PQR

Then, MN=PQ                 (CPCTC)

10=4x-2

10+2=4x

12=4x

Divide both sides by 4.

\dfrac{12}{4}=x

3=x

Similarity,

MO=PR            (CPCTC)

2y+3=21

2y=21-3

2y=18

Divide both sides by 2.

y=9

Now,

x+y=3+9

x+y=12

Therefore, the correct option is d.

A class of 20 boys and 15 girls is divided into n groups so that each group has x boys and y girls. Find x, y and n. what values
melamori03 [73]
20 = 2 x 2 x 5
15 = 3 x 5

common divisor (CD) of 20 and 15 is 5 so n should be 5 and each group has 4 boys and 3 girls.

If there are more than one CD, then there are more than one answer.

If they ask for the largest number of groups, greatest common divisor (GCD) will be the answer.
