Shamila bought 3 kg of apples. Price of apples is ₹70 per kg.
Cost of 3 kg of apples = 3 × ₹70
= ₹210
She bought 12 kg of mangoes. Price of mangoes is ₹50 per kg.
Cost of 12 kg of mangoes = 12 × ₹50
= ₹50 ÷ 2
= ₹25
She bought 34 kg of guavas. Price of guavas is ₹40 per kg.
Cost of 34 kg of guavas = 34 × ₹40
