Question

pls solve this with full explanation this is ratio and proportion ​

Answer 1

Answer: this is not a question of ratio and proportion, here is how to solve, hope its helpful to you

we will solve it by unitary method.

Step-by-step explanation:

weight of 8 sheets= 40g

''            ''   1 sheet=40/8g

                              =5g

now we know the weight of 1 sheet i.e 5g so we can easily solve this question.

no. of sheets which weights= 1.6 kg

                                               =1.6/weight of 1 sheet

      so if the weight of one sheet is in grams so we will convert 1.6 kg in

grams.

                                                  =  1.6kg x 1000

                                                  =1600g

so to find the no. of sheets which weights 1600g we will divide 1600 g with 5 g

                                                       =1600/5g

                                                       = 320

Answer=320 sheets weights 1.6kg

hope this was helpful

have a good day ahead

Answer 2

Answer:

We can solve the first part of the question with two methods -

If 8 sheets of chart paper weight is 40 kg.

Then weight of 150 chart paper will be x kg.

so we can write as -

8:40::150:x

Then we know that Product of extremes = Product of Means

then 8x=40×150

=> x = (150 × 40) ÷ 8

= 750 g {ans.}

Weight of 150 sheets is 40g= 0.04kg

then , 0.04:150 :: 1.6: x

=> Product of means = Product of extremes

=> 150x1.6 = 0.04 x

=> (150x1.6) / 0.04 = x

=> x=6000 sheets [ans.]
