(d) 448
(e) 1, 320, 000 ; 1, 260, 000
(f) 900
(g) 12, 000
Step-by-step explanation:
(a)
the pay for 1 month = 25, 000
pay for 6 years = 6 × 12 × 25, 000
= 1, 800, 000
(b)
price of 1 book = 314
price of 200 books = 200 × 314
= 62, 800
(c)
No. of students in 1 section = 40
No. of students in 1 class = 2 × 40 = 80
No. of students in the school = 8 × 80
= 640
(d)
1 small carton has = 16 pencil boxes
1 large carton has = 28 small cartons = 28 × 16 pencil boxes
= 448
(e)
Woman's earn of 1 month = 55, 000
her earn for 2 years = 2 × 12 × 55, 000
= 1, 320, 000
If she buys a scooty worth 60, 000 at the end of 2nd year , she'd be left with
= 1, 320, 000 - 60, 000
= 1, 260, 000
(f)
the least number which is exactly divisible by15,20 and 25.
=> L.C.M of (15, 20, 25) = 300
to form a perfect square
=> multiplying 300 by 3 = 900 (a perfect square)
= 900.
(g)
For 1 window, no. f bulbs required = 15
For 1 floor having 40 windows, no. of bulbs required = 15 × 40 = 600
For 20 floors, no. of bulbs required = 20 × 600
= 12, 000
Hope this helps!
