MP of Love Hearts = 40p

So cost of 7 Love Hearts = 7 *40 = 280p = Rs. 2.80

Discount = 5%

SP = MP - Discount = 40p - 5% = 40p - 2p = 38p

So SP of 7 packs = 38*7 = 266p = Rs. 2.66

Therefore, money saved = 2.80-2.66 = 14p

There is also a shorter method:

MP of Love Hearts = 40p

So cost of 7 Love Hearts = 7 *40 = 280p = Rs. 2.80

Discount = 5%

So, money saved on one pack = 5% of 40p = 2p

∴ Money saved on 7 packs = 7*2 = 14p
