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!!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
