The mean of 47 observations is 30, out of which mean of first 24 observations is 29 and mean of last 24 observations is 35. Find the 24th observation. |
|
Answer» ong>Step-by-step explanation: 24th observation is counted twice, in the first 24 and the last 24. Sum of 47 observations= 1410 Sum of first 24 observations= 696 Sum of last 24 observations= 840 Sum of last 24 observations + Sum of first 24 observations = 696 + 840= 1536 Now 1536 - 1410 = 126 24th observation is 126. LOGIC! 24th observation was calculated twice( once in last 24 and once in first 24) and once in 47 observations. 48 observations - 47 observations = the one observation that is counted twice (the 24th observation. |

Answer» ong>Answer: 1. Use Euclid’s division algorithm to find the HCF of: i. 135 and 225 ii. 196 and 38220 iii. 867 and 225 Solutions: i. 135 and 225 As you can see, from the question 225 is greater than 135. Therefore, by Euclid’s division algorithm, we have, 225 = 135 × 1 + 90 Now, remainder 90 ≠ 0, thus again using division lemma for 90, we get, 135 = 90 × 1 + 45 Again, 45 ≠ 0, repeating the above step for 45, we get, 90 = 45 × 2 + 0 The remainder is now zero, so our method stops here. SINCE, in the last step, the divisor is 45, therefore, HCF (225,135) = HCF (135, 90) = HCF (90, 45) = 45. Hence, the HCF of 225 and 135 is 45. ii. 196 and 38220 In this given question, 38220>196, therefore the by applying Euclid’s division algorithm and taking 38220 as divisor, we get, 38220 = 196 × 195 + 0 We have already got the remainder as 0 here. Therefore, HCF(196, 38220) = 196. Hence, the HCF of 196 and 38220 is 196. iii. 867 and 225 As we know, 867 is greater than 225. Let us apply now Euclid’s division algorithm on 867, to get, 867 = 225 × 3 + 102 Remainder 102 ≠ 0, therefore taking 225 as divisor and applying the division lemma method, we get, 225 = 102 × 2 + 51 Again, 51 ≠ 0. Now 102 is the NEW divisor, so repeating the same step we get, 102 = 51 × 2 + 0 The remainder is now zero, so our procedure stops here. Since, in the last step, the divisor is 51, therefore, HCF (867,225) = HCF(225,102) = HCF(102,51) = 51. Hence, the HCF of 867 and 225 is 51. |

a ladder 15m long just reaches the top of a vertical wall if the ladder makes an angle of 60° with the wall find the height of the wall |
|
Answer» em>SOLUTION :- Length of the LADDER = 15 m Ladder makes an angle of 60° with the wall. Let the triangle made be ΔPQR. Diagram is in the attachment. Then, HEIGHT of the wall = PQ Ground = QR Ladder = PR = 15M (Given) ∠PQR = 90° ∠QPR = 60° (Given) By Angle Sum Property, => ∠PQR + ∠QRP + ∠QPR = 180° => 90° + ∠QRP + 60° = 180° => 150° + ∠QRP = 180° => ∠QRP = 180° - 150° => ∠QRP = 30°
[sin 30° =
Hence, Height of the wall = PQ = 7.5 m. |

|
Answer» ong>ANSWER: (1) 135 and 225 = 45. (2) 196 and 38220 = 196. (3) 867 and 255 = 51. ᴘʟ$ ᴍᴀʀᴋ ᴀ$ ʙʀᴀɪɴʟɪᴇ$ᴛ. Step-by-step explanation: (i) 135 and 225 A- Here, 225 > 135. So, 225 = 135x1 + 90 135 = 90x1 + 45 90 = 45x2 + 0 Now, the remainder has become zero. So, the H.C.F. of 225 and 135 is 45. (ii) 196 and 38220 A- Here, 38220 > 196. So, 38220 = 196x195 + 0 Since,the remainder has now become zero. So,the H.C.F. of 196 and 38220 is 196. (III) 867 and 255. A- Here, 867 > 255. So, 867 = 255x3 + 102 255 = 102x2 + 51 102 = 51x2 + 0 Since,the remainder has now become zero. So,the H.C.F. of 867 and 255 is 51. |
