## Quant Question Of The Day: 257

**In a group of boys and girls, some people are graduates and other are not. 40% of graduates and 70% of non-graduate are boys. If there are total 40% girls in the group then what is the percent of graduates in the group.**

**33.33%****66.66%****50%****55.5%**

**Solution for Quant Question of the day: 256**

**They meet after 6 days (lcm of 2 and 3) or after 6n days**

**and Wednesday will come after 3 days or 7k+3 days**

**so 7k+3 = 6n (where k and n are integers)**

**k = 3 , then, n =4**

**hence they will meet after 7(3)+3 = 24 days for first time on a wednesday**

**and then after 42 days (lcm of 6 and 7), they will again meet (for 2nd time) on a Wednesday. It means after 66 days Viraj will have 2 crystals.**

lets total people be 100 those who grad be x now those who did not…(100-x)

boys=0.4x+70-0.7x

70-0.3x=60

x=100/0.3

(option approach is easier)
