Q11 A) Kannu made a necklace of 17 sea-shells. How many such necklaces can be made using 100 sea-shell?
B) One carton can hold 85 soap bars. Shally wants to pack 338 soap bars. How many cartons does she need for packing.
C) Manpreet wants 1500 sacks of cement for making a house. A truck carries 250 sacks at a time. How many trips will the truck make? A driver
charges Rs 500 for a trip. How much will Manpreet pay the driver for all the trips?
Answer. A) Let us this problem by the process of repeated subtraction
(1) 100 - 17 = 83
(2) 83 - 17 = 66
(3) 66 - 17 = 49
(4) 49 - 17 = 32
(5) 32 - 17 = 15
Thus. Kannu can make 5 necklaces of 17 sea-shells using 100 sea-shells He will also be left with 15 sea-shells as unused.
B)By the process Of repeated subtraction, we have
(1) 338 - 85 = 253
(2) 168 - 85 = 83
C) By the process of repeated subtraction. we have
(1) 1500 - 250 = 1250
(2) 1250 - 250 = 1000
(3) 1000 - 250 = 750
(4) 750 - 250 = 500
(5) 500 - 250 = 250
(6) 250 - 250 = 0
Thus. the truck will make 6 trips to carry 1500 sacks of cement.
Page 5
Driver's charge for 1 trip = 500 Rs
Therefore, driver’s charge for 6 trips = Rs. (500 x 6) = Rs. 3000
Thus, the money paid by Manpreet to driver = Rs. 3000.
