Last year, the ratio of the prices of two articles A and B was 3 : 5. This year, the price of A is increased by 25% and that of B is decreased by ₹210. If the ratio of the present prices of A and B is 15 : 14, then the price of A last year was:
A person borrowed a certain sum on compound interest and agreed to return it in two years in two equal annual instalments. If the rate of interest is 10% p.a. and each annual instalment is ₹4,840, then the interest paid by him was:
A boat can go \( 1 \frac{3}{5} \) km upstream and \( 4 \frac{4}{5} \) km downstream in 48 minutes, while it can go 2 km upstream and 600 m downstream in 33 minutes. How much time (in hours) will it take to go 28.8 km downstream?
In a school, the number of boys is 40% more than the number of girls. If 60% of the number of boys and 54% of the number of girls are scholarship holders, then the percentage of students in the school who are NOT scholarship holders is:
Anu earns a profit of 18% by selling an article at a certain price. If she were to sell it for ₹10.50 more, she would have gained 25%. The original cost price of 12 such articles is (in ₹):
The sum of the first 15 terms of the series \[ \frac{1}{24} + \frac{1}{104} + \frac{1}{234} + \dots = \frac{a}{b}, \text{ where HCF}(a,b) = 1. \text{ What is the difference between } a \text{ and } b? \]
If \[ \frac{\sqrt{11} - \sqrt{120}}{\sqrt{11} + 6\sqrt{2}} = A\sqrt{6} + B\sqrt{5} + C\sqrt{3} + D\sqrt{10}, \text{ then the value of } (A + B + C + D) \text{ is:} \]
The value of the expression \[ \frac{0.1\overline{8} \times 11.0 \times 0.8\overline{3}}{2.\overline{4} \times 0.\overline{6} \times 3 \times 0.1\overline{6}} \] is:
What is the value of the expression \[ \frac{(4.8)^4 + (3.5)^4 + 282.24}{(4.8)^2 + (3.5)^2 - 16.8} \]
If \( a \), \( b \), and \( c \) are three fractions such that \( a<b<c \), and if the smallest fraction is divided by the middle fraction, the result is \( \frac{15}{16} \), which exceeds the largest fraction by \( \frac{3}{16} \). If \( a + b + c = \frac{49}{24} \), then what is the difference between \( c \) and \( b \)?
In a class of 100 students, 55 students passed in Mathematics and 65 passed in English. Five students failed in both subjects. Let \( n \) be the number of students who passed in exactly one of the two subjects and \( m \) be the number of students who failed in at least one subject, then what is the value of \( (m - n) \)?
If the numerator of a fraction (in lowest form) is increased by \( \frac{1}{3} \) of itself and the denominator is decreased by \( \frac{1}{4} \) of itself, the fraction so obtained is \( \frac{21}{64} \). What is the difference between the denominator and the numerator of the original fraction?
The value of \( 5^{2 \times \frac{1}{4}} - \left( \frac{5}{32} \times \frac{3}{5} \times \frac{7}{8} \times \frac{3}{16} \right) \) is:
Let \( U = \{ 1, 2, 3, 4, 5, 6, 7, 8, 9 \} \), \( A = \{ 1, 2, 3, 4 \} \), \( B = \{ 2, 4, 6, 8 \} \), and \( C = \{ 3, 4, 5, 6 \} \), the number of elements in \( (A \cap C) - (B - C) \), where \( (A \cap C)' \) and \( (B - C)' \) are the complements of \( (A \cap C) \) and \( (B - C) \), respectively is:
Let \( U \) be the universal set, \( A \), \( B \), and \( C \) are the sets such that \( C \) is a subset of \( A \) and \( B \cap C = \emptyset \). If \( n(U) = 105 \), \( n(A) = 58 \), \( n(B) = 50 \), \( n(A \cap B) = 20 \) and \( n(A \cap C) = 32 \), then \( n(A \cup B) - n(B \cap C') = ? \)
Let \( A = \{1, 2, 5, 6\} \), \( B = \{1, 2, 3\} \), and \( C = (A \cap B) \cup (B \cap A) \). Which of the following is INCORRECT?
