$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star$

$\star\;{\underline{\underline{\sf{\pink{QueStion\;1\;:}}}}}$

which ratio is greater?

1)5:7 or 8:11

2)11:21 or 13:25

3)9:16 or 15:22

$\star\;{\underline{\underline{solution:-}}}$

1)5:7 is greater then 8:11

2)11:21 is greater than 13:25

3)15:22 is greater than 9:16

$\star\;{\underline{\underline{\sf{\pink{QueStion\;2\;:}}}}}$

Jai's class has 8 boys and 10 girls .ashu's class has 6 boys and 8 girls.which class has higher ratio of boys to girls.

$\star\;{\underline{\underline{solution:-}}}$

Jai's class :- 8:10 = 4:5

ashu's class :- 6:8 = 3:4

therefore Jai's class has the higher ratio of boys to girls.i.e 8:10

$\star\;{\underline{\underline{\sf{\pink{QueStion\;3\;:}}}}}$

the ratio of boys to girls in a class is 3:2 .if there are 33 boys .how many girls are there ?

$\star\;{\underline{\underline{solution:-}}}$

ratio of boys to girls = 3:2

boys = 33

girls = 3:2 :: 33: X

product of means = product of extremes

girls = 33×2/3×x

girls = 11×2/1×x

girls = 22/1

= 22

therefore,

the number of girls in the class is 22

$\star\;{\underline{\underline{\sf{\pink{QueStion\;4\;:}}}}}$

the ratio of number of Sonia's beads to the number of nandini's beads is 5:7 .if Sonia has 65 beads how many beads does Nandini have?

$\star\;{\underline{\underline{solution:-}}}$

the ratio of number of Sonia's beads to the number of nandini's beads = 5:7

Sonia's beads= 65

nandini's beads= 5:7::65:X

product of means = product of extremes

65×7/5×x

13×7/1×x

=91

therefore,

Nandini have 91 beads

$\star\;{\underline{\underline{\sf{\pink{QueStion\;5\;:}}}}}$

the length and breadth of a classroom is in the ratio of 3:5 the breadth of the classroom . find the length?

$\star\;{\underline{\underline{solution:-}}}$

the length and breadth of a classroom is in the ratio of 3:5

length = 20m

breadth=

3:5::20:X

product of means = product of extremes

3×20/5×x

60/5× X

X= 30

therefore,

the breadth of the classroom = 30m
