Given photograph size, x1 = 50000
Length of bacteria, y1 = 5 cm
If x2 = 1 then y2 = ?
Here photograph size and length of bacteria in direct proportion
Hence x1/y1 = x2/y2
50000/5 = 1/ y2
10000 = y2
10³=y2 which is the actual size of the bacteria
this is definitely the right answer

option is also available a.1000 cm b.10 power _3cm c.10 power _ 3 cm d.10_2cm
c.10 power _4
ok then then the answer is b. 10power3 which is y2 = 10000=10power 3
