\nThe capacity of a water tank is 300 litres. Express its capacity in millilitres.
\nSolution:
\nWe know that
\n1 litre = 1000 mL
\n\u2234 300 litres = 300 x 1000 mL = 3,00,000 mL
\nHence, the capacity of water tank = 3 lakh millilitres.<\/p>\n
\nWhat is the successor of greatest 6-digit number?
\nSolution:
\nGreatest 6-digit number = 999999
\nSuccessor of it = 999999 + 1 = 1000000
\ni. e., smallest 7-digit number.
\nHence, the required successor = 10,00,000.<\/p>\n
\nWhat is the place value of 7 in 1743?
\nSolution:
\nLet us write 1743 in its expanded form
\n1743 = 1000 + 700 + 40 +3
\nPlace value of 7 = 700
\nHence, the place value of 7 = 700.<\/p>\nKnowing Our Numbers Class 6 Extra Questions Short Answer Type<\/h3>\n
\nOf 7,12,540 and 71,25,400 which number is greater and by how much?
\nSolution:

\nThe distance between the school and Reena\u2019s house is 1 km 480 m. Everyday she walks both ways. What distance does she cover in 6 days of a week?
\nSolution:
\nDistance covered when she walks one way = 1 km 480 m = 1480 m
\nTherefore, the distance covered when she walk both ways in a day = 1480 x 2 m = 2960 m
\nTotal distance covered by Reena in 6 days = 2960 x 6 m = 17760 m or 17 km 760 m.<\/p>\n
\nSimplify: 36 \u00f7 [5 + {4 x 5 \u00f7 2}]

\nTo stitch a pant 1 m 15 cm cloth is needed. Out of 36 m cloth, how many pants can be stitched and how much cloth will remain?
\nSolution:
\n
\nCloth required to stitch 1 pant = 1 m 15 cm
\n= 100 cm + 15 cm [\u2235 1 m = 100 cm]
\n= 115 cm
\nTotal cloth = 36 m = 36 x 100 cm = 3600 cm
\nTherefore number of pants stitched = \\(\\frac { 3600 }{ 115 }\\)
\nHence, 31 pants can be stitched and cloth left over is 35 cm.<\/p>\n

\nThere are two factories located at place P and the other at place Q. From these factories, a certain commodity is to be delivered to each of the depots situated at A, B and C. Weekly production of commodity by P and Q are 120 kg and 150 kg respectively. Weekly requirement of commodity by A, B and C are 80 kg, 90 kg and 100 kg respectively. P delivers 60 kg to A, 40 kg to B and 20 kg to C. How much amount of the commodity should Q deliver to A, B and C to meet their requirement? If the rate of the commodity is ? 20 per kg, find the total amount to be paid to P and Q.
\nSolution:
\n
\nAmount of commodity delivered by P to A = 60 kg
\nAmount of commodity delivered by Q to A = 80 – 60 = 20 kg
\nAmount of commodity delivered by P to B = 40 kg
\nAmount of commodity delivered by Q to B – 90 – 40 = 50 kg
\nAmount of commodity delivered by P to C = 20
\nAmount of commodity delivered by Q to C = 100 – 20 = 80 kg.
\nNow Amount of money to be paid to P by A, B and C = \u20b9( 60 x 20 + 40 x 20 + 20 x 20)
\n= \u20b9 (1200 + 800 + 400)
\n= \u20b9 2400
\nand amount of money to be paid to Q by A, B and C
\n= \u20b9 (20 x 20 + 50 x 20 + 80 x 20)
\n= \u20b9 (400 + 1000 + 1600) = \u20b9 3000
\nHence, the total amount
\n= \u20b9 2400 + \u20b9 3000 = \u20b9 5400.<\/p>\nExtra Questions for Class 6 Maths<\/a><\/h4>\n
