ਜੇਕਰ x3339 ਸੰਖਿਆ 11 ਨਾਲ ਭਾਗਯੋਗ ਹੈ, ਤਾਂ x ਅੰਕ ਕੀ ਹੋਵੇਗਾ?
A2
B4
C5
D3
Answer & Solution
Correct answer: C. 5
1। 11 ਦੁਆਰਾ ਵਿਭਾਜਯੋਗਤਾ: (ਅੱਡ ਸਥਾਨਾਂ 'ਤੇ ਅੰਕਾਂ ਦਾ ਜੋੜ) - (ਸਮ ਸਥਾਨਾਂ 'ਤੇ ਜੋੜ) 11 ਦਾ ਗੁਣਜ ਹੈ। 2। x3339 ਲਈ, ਸੱਜੇ ਪਾਸੇ ਤੋਂ: ਅੱਡ ਸਥਾਨ 9, 3, x; ਸਮ ਸਥਾਨ 3, 3। ਅੱਡ ਜੋੜ = 12 + x, ਸਮ ਜੋੜ = 6। 3। ਅੰਤਰ = 6 + x। ਵਿਭਾਜਕਤਾ ਲਈ, 6 + x = 11, ਇਸ ਲਈ x = 5। _ਸਰੋਤ: RRB ਸਮੂਹ D CEN-02/2018 PYQ, Q.71._
