Answer» Correct Answer - Option 3 : 6 GIVEN: When four positive numbers a, b, c, and d are divided by 41, the remainders are 3, 4, 6, and 2, respectively. CONCEPT: Dividend = Divisor x Quotient + Remainder CALCULATION: a = 41w + 3, b = 41x + 4, c = 41y + 6, d = 41z + 2 Here, 41w, 41x, 41y and 41z is divisible by 41. So, according to question – (5a + 6b – 2c + 10d) ⇒ (15 + 24 – 12 + 20) ⇒ 59 – 12 ⇒ 47 When (5a + 6b – 2c + 10d) is divided by 41. ⇒ Remainder (47/41) = 6 |
