Two-third of a positive number and 16/216 of its reciprocal are equal. Find the positive number.
Let the positive number be x.
Then, 2/3 x = 16/216 × 1/x
x2 = 16/216 × 3/2
= 16/144
x = v16/144 =4 /12.
The unit digit in the product (624 × 708 × 913 × 463) is:
In an entrance exam, 3 marks is awarded for every correct answer and (-1) for every wrong answer. If a student gets 38 marks after attempting all questions, find the number of questions answered correctly if the total questions were 70.
Let x be the number of questions answered correctly. Hence, number of questions whose answer were wrong = (70 – x)
3 × x + (70 – x) × (-1) = 38
4x = 38 + 70 = 108
x = 27
