alleryਇੱਕ ਕਸਬੇ ਵਿੱਚ, 60 ਪ੍ਰਤੀਸ਼ਤ ਨੇ ਪੇਪਰ ਪੜ੍ਹਿਆ X, 40 ਪ੍ਰਤੀਸ਼ਤ ਨੇ ਪੇਪਰ ਪੜ੍ਹਿਆ Y ਅਤੇ 20 ਪ੍ਰਤੀਸ਼ਤ ਨੇ ਦੋਵੇਂ ਪੜ੍ਹੇ। ਕਿੰਨੇ ਪ੍ਰਤੀਸ਼ਤ ਨੇ ਕੋਈ ਵੀ ਨਹੀਂ ਪੜ੍ਹਿਆ?
A10
B20
C15
D25
Answer & Solution
Correct answer: B. 20
ਘੱਟੋ-ਘੱਟ ਇੱਕ ਦੇ ਪਾਠਕ = 60 + 40 - 20 = 80 ਪ੍ਰਤੀਸ਼ਤ, ਇਸ ਲਈ 20 ਪ੍ਰਤੀਸ਼ਤ ਦੋਵਾਂ ਵਿੱਚੋਂ ਕਿਸੇ ਨੂੰ ਵੀ ਨਹੀਂ ਪੜ੍ਹਦੇ।
