Arrange the following steps of construction of an angle 120° in a correct order.
Steps of construction:
(1) Draw a ray PQ.
(2) With B as a centre, again draw an arc to intersect the first arc at C.
(3) With P as a centre and a convenient radius, draw an arc to intersect at A.
(4) Join CP to get the required angle. ∠CPQ measures 120°.
(5) With A as a centre, draw an arc with the same radius to intersect the previous arc at B.
Read the statements carefully and select the correct option.
Statement-I : If carpet is laid on the floor of a room 10 m by 6 m, leaving a border 1 m wide all around it, then the perimeter of the carpet is 24 m.
Statement-II : The perimeter of a rectangle is 12 cm. If the measure of length is cm more than its breadth, then the breadth of the rectangle is 2.25 cm.
ABoth Statement-I and Statement-II are true.
BStatement-I is true but Statement-II is false.
CStatement-I is false but Statement-II is true.
DBoth Statement-I and Statement-II are false.
Fill in the blanks.
(i) When two negative integers are added, we get a__(P)__ integer.
(ii) The number of integers between –16 and –2 is __(Q)__.
(iii) When two __(R)__ integers are added, we get a positive integer.
ANSWER SHOULD BE C. BUT, IN SOLUTION, ANSWER FOR Q IS 14. IT IS 13 AS PER SEEN IN NUMBERLINE.
