1. The number of stamps in Ziko's collection is 75% of the number in Pallab's collection. If Pallab has 80 more stamps than Ziko, how many stamps do they have altogether?
- A. 320
- B. 320
- C. 320
- D. 320
Answer: Option C
Explanation:
let, pallab has = X stamps
ziko has = 0.75X stamps
pallab has x - 0.75x = 0.25x more stamps than than ziko.
apq,
0.25x = 80
x = 320
pallab has = 320 stamps
ziko has = 320x.75 = 240
together they have = 320 + 240 = 560
