Dear Student, ∵ cost of 18 packets of washing poweder of 1 5 kg = Rs 1242∴ cost of 1 packet of washing poweder of 1 5 kg = 124218 = Rs 69Then cost of 1 kg washing poweder = 691 5 = Rs 46∴ cost of 14 packets of washing poweder of 2 kg = 46 × 2 × 14 = Rs 1288 Regards

Pls solve the 10 one

Dear Student,
$∵ \cos t o f 18 p a c k e t s o f w a s h i n g p o w e d e r o f 1.5 k g = R s 1242 ∴ \cos t o f 1 p a c k e t o f w a s h i n g p o w e d e r o f 1.5 k g = \frac{1242}{18} = R s 69 T h e n \cos t o f 1 k g w a s h i n g p o w e d e r = \frac{69}{1.5} = R s 46 ∴ \cos t o f 14 p a c k e t s o f w a s h i n g p o w e d e r o f 2 k g = 46 \times 2 \times 14 = R s 1288$
