8. Find the H.C.F. of 513, 1134 and 1215.

Answer»

First find prime factors of 513,1134, and 1215

1215= 3×3×3×3×3×5= 3^5 ×^1

1134= 3×3×3×3×2×7= 3^4×2^1×7^1

513= 3×3×3×19= 3^3×19^1

H.C.F= 3^3 = 3×3×3= 27

Hence the HCF of 513,1134 and 1215 is 27

(a) 33-%(b)372%(d)(c) 40%45%The price of an article has been reduced by 25%. In order terestore it to theoriginal price, the new price must be increased by2

Answer»

Old price = xNew price = y

According to question y = x - (25% of x)y = x - (25/100 × x)y = x - x/4y = 3x/4 ……(1)

Now, in order to restore the original price (x) the new price (y) should be increased by zx = y + z4y/3 = y + z ……[∵ from (1)]z = 4y/3 - yz = y/3

∴ New price should be increased by 1/3rd
