Answer:
(d) 4,20,000
Step-by-step explanation:
It is Given that :
Total number of candidates who gave the test = 6,30,000
No. of candidates who answered Question A correctly =  3,30,000 candidates.
No. of candidates who answered Question B correctly =2,50,000 candidates
No. of candidates who answered Question C correctly 2,60,000 candidates.
No. of candidates who answered Both questions A and B correctly = 1,00,000 candidates.
No. of candidates who answered Both question B and C correctly = 90,000 candidates.
No. of candidates who answered  Both questions A and C = 80,000 candidates.
Let x =  Total number of candidates who answered all questions correctly
We, know  630000 =  2x+ 150000 +100000 +80000 +60000+ 90000 +90000
630000 -570000 = 2x
x = 30000
The students failed to clear the test = 150000+ 60000+ 90000 +4x
= 300000 +4 ×30000
= 420000
