Ans 1: (Master Answer)
(A)
Cost of 12kg of coffee she sold = 12 x 56 = Rs. 672
Cost of 18kg of coffee she sold = 18 x 46 = Rs. 828
Average selling price
= Rs 50
(A)
Cost of 12kg of coffee she sold = 12 x 56 = Rs. 672
Cost of 18kg of coffee she sold = 18 x 46 = Rs. 828
Average selling price
= Rs 50
(D): The digit at ones place = 2
The digit at tens place = 2+4 = 6
The digit at hundreds place = Greatest one digit number = 9
Therefore, the number is 962.
(B)
x = 180 - (100 + 25) [Sum of interior angles in triangle in 180°]
= 55°
y = 25° [Alternate angle]
m = x = 55° [Corresponding angles]
w = 180º - (55º + m) [Sum of interior angles in triangle in 180°]
= 180º - (55º + 55º) = 70º
w = z + 25º [Corresponding angles]
z = 70º - 25º = 45°
x + y = 55º + 25º = 80°
w - y= 70º - 25º = 45°
