can help me any one . If ₹640 is divided between Bishu and Arpana in the ratio of 5 : 3 , lets find how many each would get.​

a/q ratio 5:3 total money is divided in 8 parts so 1 part =rs 80 so b&a got 80×5=400 & 80×3 =240 resp

first find the total = 5+3=8

now 5/8×640 =5×80 = 400 rupees

3/8×640 =3×80 = 240 rupees

so Bishu gets 400 rupees and Arpana gets 240 rupees.

hope you understood!!

its definatley   this on your answer choice?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
