b)
a)
Step-by-step explanation:
15)
r = 28 cm
distance = 352m = 35200 cm
Now,
how many times = circumference of wheel
= total distance / circumference
= 35200 / 2πr
= 35200 / 2 × 22/7 × 28
= 35200 / 2 × 4 × 22
= 35200 / 176
= 200
ans c) 200
16)
Here,
let the common factor be x
So,
ratio = 8x : 9x
Ram's age = 8x
& Shyam's age = 9x
And,
8x + 9x = 68 ...given
17x = 68
x= 68/17
x = 4
So,
Ram's age = 8x
= 8(4)
= 32
Shyam's age = 9x
= 36
Now,
after 10 years,
= 8x + 10 & 9x + 10
= 32 + 10 & 36 + 10
= 42 & 46
=21 : 23
ans b) 21 : 23
17)
(24.8% of 1338) - (15.5% of 945)
= (24.8 / 100 × 1338) - ( 15.5 / 100 × 945)
= 331.824 - 146.475
= 185.349
ans a) 185.349
