The cost of 3kg sugar is ₹90

So, cost of 1 kg sugar = 90/3 = ₹30

Therefore the cost of 8kg of sugar = 8 (30) = ₹240

96% are passed . Therefore 4% are failed. Let no of candidates be x. 4% of x = 50 [4÷100] * x=50 X=50*100÷4 .....shifting 100 and 4 X=50*25 X=1250

Mansi R 5 years, 9 months ago

A rational number is a number which can be written in the form of p/q (ratio) where the denominator(q) is not equal to zero. This implies that it can be represented in the form of a fraction. Thus, every rational number has a numerator and a denominator, that is, one integer divided by another integer (excluding zero).
