rocky620 · Answer

Total balloons = 40 (only Red / Yellow)

Red = 30% = 12
Yellow = 40-12=28

Yellow with strings = 28*.25 = 7
Yellow without strings = 28-7 = 21

IMO Option E

30% red means 12 red balloons; Rest 28 balloons are yellow.
a quarter of the yellow balloons have strings: 7 yellow balloons have strings, and 21 yellow balloons don't have strings.

Answer E.

Harsh9676 · Answer

Ans E

Given Total no of Balloons are 40

Of which, # Blue = 12 (30% of 40) and # Yellow = 28

# Stringed Balloons = 7 (1/4 of 28) ; So # the balloons with no strings = 21

ananya3 · Answer

IMO E

total = 40
red = 0.3 * 40 = 12
yellow = 0.7 * 40 = 28
1/4 * yellow = 7 (yellow with strings)
yellow without strings = 28 - 7 =  21

anjanita · Answer

The answer is E

The total number of balloons are 40,

Therefore the total number of yellow balloons = 40*(70/100 = 28

1/4th of the yellow balloons have strings i.e. 28/4 = 7

Therefore, the number of yellow balloons do not have strings = 28-7 = 21

TarunKumar1234 · Answer

Yellow Ballons = 40* 70% = 28 Without strings= 3/4*28= 21, So, I think A.
