Answer:
If 3/10 failed, then, 7/10 succeded
and number of more passed than failed = 7/10 - 3/10 = 4/10
it is given that who passed exceeds the number of failures by 260,so,
260=4/10
260/4 = 1/10
65=1/10
total number of candidates = 65 × 10 = 650
total number of failures = 3/10 = 3 × 65 = 195
total number of passed candidates = 7 × 65 = 455
