Question
Which of the following is the greatest number that
divides 72 and 119 and leaves 3 and 4 as respective remainders?Solution
To find the greatest number that divides 72 and 119 and leaves remainders 3 and 4, respectively, follow these steps: Adjust the numbers by subtracting the remainders: 72 - 3 = 69 119 - 4 = 115 Find the greatest common divisor (GCD) of 69 and 115. Use the Euclidean algorithm: 115÷69=1 (quotient),115−69=46 69÷46=1 (quotient),69−46=23 46÷23=2 (quotient),46−46=0 The GCD is 23. Thus, the greatest number that divides both 72 and 119, leaving remainders 3 and 4, respectively, is 23.
What approximate value should replace the question mark?
12.45% of 640.20 − 60% of 2500 = ? − 9000.10
`[(7.99)^2 - (13.001)^2 + (4.01)^3]^2=` ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
What value should come in place of question mark (?) in the following question. (You need not to calcualte the exact value)
?/647 = 226/ ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
A, B & C have Rs.1550 together. If they divide the money in the ratio 1:3:1 respectively. Find the difference of amount received by B and C.
What approximate value should come in the place of (?) in the following questions?
∛(92.8 + √1025) * ? = 16.06% of 750
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
√784 × 3 + (713.99 ÷ 6.98) = ?% of 619.99
11.11% of (123.45 + 234.56) + 10.01³ - (5.05 of 7.07) = ? of (88.88 - 33.33)
