Answer:

sunita's height = 154 cm

Step-by-step explanation:

Mean height of shweta smriti and sunita = 148 cm

Total height of shweta smriti and sunita = 148 *3 = 444 cm

Height of shweta + Smriti = 150 + 140 = 290 cm

Height of Sunita = height of shweta smriti and sunita - Height of shweta + Smriti

Height of Sunita = 444 - 290 = 154 cm

sunita's height = 154 cm
