Ques 1.<\/span>
\nSix bells commencing tolling together toll at intervals of 2, 3, 6, <\/span>8 , 10 and 12 seconds respectively.In 30 minutes how many times do they toll together? <\/span><\/p>\n

Ans 1.<\/span><\/p>\n

L.C.M of 2, 4, 6, 8, 10 and 12 is 120. so, the bells will toll together after 120 seconds i.e. 2 <\/span>minutes . In 30 minutes the bells toll together 30\/2 + 1 times i.e. times.<\/span>
\nQues 2.<\/span>
\nThe H.C.F of two numbers is 11 and their L.C.M is 7700. If one of these numbers is 275, then find the other number. Ans 2.<\/span><\/span><\/p>\n

Product of two <\/span>number s = product of their H.C.F. and L.C.M. required number = 11 X 7700\/275 = 308<\/span>
\nQues 3.<\/span>
\nA gardener had a number of shrubs to plant in <\/span>rows . At <\/span>first he tried to plant 8, then 12 and then 16 in a row but he always had 3 shrubs left with <\/span>him . On trying 7 shrubs he was left with none.Find the total number of shrubs.<\/span><\/p>\n

Ans 3.<\/span><\/p>\n

L.C.M of 8,12,16 = 48 Now, 48 x 1 + 3 = 51 – not divisible by 7 48 x 2 + 3 = 99 – not divisible by 7 48 x 3 + 3 = 147 – not divisible by 7 Required number = 147<\/span>
\nQues 4.<\/span>
\nThree measuring rods <\/span>are 64 cm,80 cm and 96 cm in <\/span>length . What is the least length of cloth that <\/span>can can be measured <\/span>exact number of times using any one of these rods? (a) 9.60 m (b) 8 m (c) 9.60 cm (d) 96 m Ans 4. 9.60 m<\/span><\/p>\n

Ans 4.<\/span><\/p>\n

9.60 m<\/span><\/p>\n

Ques 5.<\/span>
\nThe sum of two numbers is 528 and their H.C.F is 33. What is the number of pairs of such <\/span>numbers ? (a) 4 (b) 12 (c) 8 (d) 6 <\/span><\/p>\n

Ans 5. <\/span><\/p>\n

4 <\/span>Hint : Let the number be 33x and 33y where x and y are co-prime.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
