Question

If 10 planters can plant 8 fields in 4 days. How many days are required to plant 18 field by 12 men?

Answer 1

Answer:

12 workers.

simple maths.

8*6=48

x*4=48

x=48/4=12

explanation:

8 (workers) * 6 (hours) = 48 (fixed value - amount of work - no unit)

then:

x (workers) * 4 (hours) = 48

x = 48/4 = 12 (workers)

question for you:

if 5 sinks need 20 hours to fill a container, then how many hours do we need to fill two containers using 10 sinks?

tip: notice i said two containers, so that’s double the fixed amount.

Answer 2

Step-by-step explanation:

$.$

∠A+∠B=180

o

[ Sum of adjacent angles in rhombus is 180

o

]

⇒ 45

o

+∠B=180

o

∴ ∠B=135

o

⇒ ∠A=∠C and ∠B=∠D [ Opposite angles are equal ]

⇒ Draw a line segment AB=4cm

⇒ Take A as center and draw angle of 45

o

⇒ Cut off AD=4cm

⇒ Take B as center and draw angle of 135

o

⇒ Cut off BC=4cm

⇒ Join CD

∴ ABCD is a required rhombus.
