$\red { ❥︎ \: \fbox {Ans 1 :}}$

$4 × \frac {2}{7} = \frac {8}{7}$

➡ B) $\bf {\frac{8}{7}}$

Let the third angle be x.

Sum of interior angles of triangle = 180°

50° + 64° + x = 180°

114° + x = 180°

x = 180° - 114°

x = 66°

➡ D) 66°

$\red { ❥︎ \: \fbox {Ans 3 :}}$

0.008 × 1000

= 8

➡ C) 8

$\red {❥︎ \: \fbox {Ans 4 :}}$

Girls = 60

Boys = 70

Total students = Girls + Boys = 60 + 70 = 130

Fraction = Boys/Total students = 70/130 = 7/13

➡ C) 7/13

$\red {❥︎ \: \fbox {Ans 5 :}}$

1 km = 1000m

1m = 1/1000km

So, 180m = 180/1000 = 0.18 km

➡ A) 0.18 km

Let the number be x.

(-4) × x = (-32)

x = (-32) ÷ (-4)

x = 8

➡ (-4) × 8 = (-32)

$\red {❥︎ \: \fbox {Ans 7 :}}$

y/6 = - 3

y = (-3) × 6 = (-24)

➡ y = (-24)

$\red {❥︎ \: \fbox {Ans 8 :}}$

Complementary angle = 90°

So, complementary angle for 45° = 90° - 45° = 45°

➡ 45°

$\red {❥︎ \: \fbox {Ans 9 :}}$

➡ Parallel

$\red {❥︎ \: \fbox {Ans 10 :} }$

➡ 180°
