Answer: 46
Explanation Let's find the pattern in the number series: 1, 6, 13, 22, 33, ? Differences between terms: 6 - 1 = 5 13 - 6 = 7 22 - 13 = 9 33 - 22 = 11 The differences are increasing by 2: 5, 7, 9, 11... Next difference: 13 So, next term = 33 + 13 = 46

اگر 6 آدمیوں کی 15 دن کی اجرت 2100 ہے تو 9 آدمیوں کی 12 دن کی اجرت معلوم کریں؟
Answer: 2520
Explanation Given: The wages of 6 men for 15 days be Rs. 2100 Calculation: As the wages of 6 men for 15 days be Rs. 2100 The wages of 1 man for 15 days = Rs. 2100/6 = Rs. 350 And, the wages of 1 man for 1 day = Rs.350/15 Now, the wages of 9 men for 12 days = (Rs.350/15) × 9 × 12 = Rs.2520 ∴ The wages of 9 men for 12 days is Rs.2520 .
Answer: 4
Explanation The number of subsets of a set with 2 elements, such as (x, y), is 2^2 = 4. Here are the 4 subsets: 1. {} (the empty set) 2. {x} 3. {y} 4. {x, y} (the original set itself) This is because each element (x and y) can either be included or excluded from the subset, giving us 2 options for each element, and therefore 2^2 = 4 total subsets.
Answer: Rs. 20
Explanation Let's denote the daily earnings of A, B, and C as a, b, and c respectively. We are given: a + b + c = 150 ... (1) a + c = 94 ... (2) b + c = 76 ... (3) Now, add equations (2) and (3): (a + c) + (b + c) = 94 + 76 a + b + 2c = 170 Now, subtract equation (1) from this: (a + b + 2c) - (a + b + c) = 170 - 150 c = 20
