1. Answer : (B) Solution :-
Let value of B is x. / माना B का मान x है |
130 × 3 = x + x + 20 + x + 20 + 50
390 = 3x + 90
3x = 300
x = 100
C = 100 + 20 + 50 = 170
2. Answer : (C) Solution :-
According to the question/ प्रश्नानुसार,
20% + 15 = 30% – 32
10% = 32 + 15 = 47
100% = 470
Passing marks/ उत्तीर्ण अंक = 141 – 32 = 109
3. Answer : (D) Solution :-
Such numbers are always divisible by 101. / ऐसी संख्याएं हमेशा 101 से विभाजित होती हैं |
4. Answer : (A) Solution :-
Let the three consecutive odd numbers be x, x + 2, x + 4. / माना क्रमागत विषम संख्याएं x, x + 2, x + 4 हैं |
According to the question/ प्रश्नानुसार,
[(x + x + 2 + x + 4)/3] = (1/3) x + 12
3x + 6 = x + 36
2x = 30
x = 15
5. Answer : (D) Solution :-
30% of P/P का 30% + 40% of Q/Q का 40% = 80% of Q/Q का 80%
30% of P/P का 30% = 40% of Q/Q का 40%
3P = 4Q
P: Q = 4: 3
Required/अभीष्ट % = [(3/4) × 100] = 75%
