### Solutions and Answers :

**Solution :**

No.of students cleared UPSC = 197

No.of students cleared BANK = 207

No.of students cleared SSC =268

No.of students only cleared UPSC = X

No.of students only cleared BANK = Y

No.of students only cleared SSC = Z

No.of students cleared all 3 exams = K

No.of students cleared UPSC and BANK = 40

No.of students cleared UPSC and SSC = 49

No.of students cleared BANK and SSC = 35

X+K = 197-(40+49) = 108

Y+K = 207-(40+35) = 132

Z + K = 268 - ( 49+35) = 184

X+Y+Z+K = 500 - (40+49+35)= 376

From above equations

X=84 ; Y =108 ; Z = 160 ; K = 24

**Answers :**

**1.2**

K=24

**2.2**

Only UPSC = 84

Total no.of students = 500

% of only UPSC cleared = 84*100/500 = 16.8%

**3.5**

Who cleared at least two examination = 40+49+35+24=148

**4. 1**

who cleared BANK ,but not SSC = 148*100/500 = 29.6%

**5. 4**

= 84+108+160+160=352
